I've had this happen to me once....smoked probably 6 bowls of BC juicy fruit (first time I toked for 3 weeks). I was around a bunch of people I never knew, and was too stoned to even give a rat's ass about socializing with them. Well I did, I thought I should of, but I was too stoned to make a move.

This is a very common occurrence. Happens to many people all the time.
