Don't worry; you never have.

It seems some people don't even consider it teasing. At least, that's what someone tried to say to me once, that it was more like a reflex response meant to--I dunno--make the situation less awkward or something?

Or maybe they just consider it free game, like monshu teasing me for my lateness or me making fun of his inability to catch. That's why I listed it here: It seems a trivial thing for most people, who don't realise how much cruel mockery I suffered on account of it when I was a schoolchild.
