Pun intended on the subject.

but no, i dont mean actual ticks, here where im from, these are things that you have to do on a day to day basis, or you feel...odd. like if a persons tick is to go on the internet at least once in a day, and they dont do it for one day, that one day, theyll be like

-shivers and taps foot-. See what I mean?
My tick is that I have to have a pencil with me everywhere. NO PEN! PENCIL...i dont feel complete without it. ^^;
