It really, really depends on the situation for me, plus my mood at the time.

A lot of the times, I'm pretty chill. So long as I have something to occupy myself with, be it my own thoughts or my cellphone or my 3DS (Lol, when they're not totally dead), I am pretty patient.

Take away my technology though and I may not be quite so patient. XD

Plus it depends on the setting. If I'm having to wait at, say, a grocery store, I like to just walk around aimlessly.
