totally stupid annoying habit I have

But still kinda fun.

I can’t help it. Every time I walk past someone in the hall; I have to stick my tongue out or make a face. As we walk by each other, I’ll smile and say hello; but once they have passed…my face just “automatically” contorts into some idiotic goofy expression.
EVERY…SINGLE…TIME…

Its been going on for years; so far I’ve never been caught…I think.

If you have never been caught, who are you annoying?

I think the poster finds it annoying that s/he must do it every time.
