Private Grammars: What Toc Toc Taught Me About Language and Obsessions

An article by Stella Bullo on language, obsessions, and the private grammars we use to sustain our worlds.

Dr. Stella Bullo

What’s your OCD? Mine, if I have one, leans toward symmetry. It isn’t disabling, but it’s there, like a quiet compass that twitches when something tilts. A picture slightly askew bothers me, a line of chairs with one out of place, a shelf where a single book breaks the line. And although it may seem a minor detail, I know that this search for order isn’t only so the picture looks symmetrical and aligned, it’s also so I can feel well, to give shape to my life, to hold on to what I can control.

While rehearsing Toc Toc with the independent theatre group in Berrotarán, the town where I live, that small quirk stopped being a personal curiosity and became a line of thought. Sharing the stage with characters who embody different manifestations of obsessive compulsive disorder, I realised that what separates us isn’t so much the nature of our obsessions as their intensity and visibility.

The play foregrounds an uncomfortable fact: the world we see and touch is, to a great extent, a construction shaped by our fears and conditioning. Language is the tool with which we build that reality and, at the same time, the proof that legitimises it. Sometimes its role is explicit, as with the person living with Tourette’s whose speech inevitably breaks the rules of politeness. In other cases it’s subtler, like the one who prays almost frantically to feel protected, even from her own actions.

And in the end, we all use language to hold up a world we can inhabit. In Toc Toc, each character reminded me that language is not only communication: it is shelter, boundary, and a personal map that, ultimately, leaves us with a lesson.

Private Grammars: Six Portraits of Language on Stage

For the person with Tourette’s, language is a living animal that won’t be tamed. Words spill out unfiltered, breaking into conversation and tearing through social and linguistic etiquette we take for granted. They remind us we don’t always choose what we say.

For the arithmomaniac and hoarder, every dialogue becomes meticulous accounting. Their world is an archive. They speak like someone taking inventory: everything must be counted, recorded, filed. Each number is a stake pinning reality in place. Counting is retaining, and retaining is refusing to let anything, object or word, slip into oblivion. Language here doesn’t just communicate; it conserves.

For the cleanliness-obsessed, each line comes with a burst of spray alcohol. Every action follows a sacred protocol. Their lexicon swarms with bacteria, viruses, contamination. They measure distance as they speak, avoiding any invasion of their space. Language becomes a perimeter of safety.

For the compulsive checker, language is a loop of verification. Between one check and the next, they pray. Prayer is a double lock, a spell that protects even from oneself. Language can be a ritual act: a way to quiet uncertainty, even if certainty exists only in the mind.

For the repeater who says everything twice, it’s not emphasis or carelessness, it’s survival. In their mind, repeating is how they make sure the world doesn’t come undone. Each doubled line is like a second knot on the rope that holds reality. Language as a charm against fear, a way to keep the world tied to a safe point.

From Stage to World: Empathy, Humour and the Value of Performance

For the symmetry fanatic who aligns objects with millimetric precision and lives in the prison of straight lines, every deviation is a threat. They fall in love with the repeater because, to them, repetition is the epitome of symmetry: two identical sentences side by side, like mirrored reflections. I recognise myself there: external order as projection—and at times illusion—of the inner order we seek. Visual harmony can mirror the desire for inner harmony, and sometimes that symmetry is simply a refuge we manufacture to keep ourselves standing.

Toc Toc left me thinking that our words don’t always describe reality as it is, but as we need it to be to live in it. Perhaps your OCD isn’t counting, praying, or repeating, but surely you have a small ritual, minimal, intimate, that, if taken away, would leave you exposed. Mine, as I said, is symmetry. Yours, who knows, may hide in the way you speak, in the pause you always stretch, or in the silence you never break.

Being part of this play reminded me that theatre is also a laboratory for empathy: by embodying others, for a moment we live inside their obsessions, their fears, and their internal logics. Laughing together at those exaggerations is not mockery, but a recognition that, to some degree, we are all like that. When used well, humour opens the door to understanding and disarms judgment. Performance allows us, in the end, to return to the real world a little more aware of our own quirks, more tolerant of those of others, and grateful for that safe space where play and truth can coexist.
