I came round a corner in my wheelchair yesterday to find a man putting up a large show poster (a very familiar sight in Edinburgh). In fact he’d just finished.

My tics shouted “It’s not straight!”

He looked mortified, stood back to look, and then laughed when I explained that I had Tourettes, and that he’d actually done a perfectly good job.

If you’re in Edinburgh yourself, look out for our BIBL posters which are going up, straight or otherwise, as we speak.
