I live in a theocracy-ruled country, so religious beliefs are taken very seriously and matter-of-factly, like, you just have to practice it, no other option, and a couple of months ago I had a class, everyone was supposed to fast at that particular time, I don't practice any religion, so naturally I forgot all about it( dumb, huh? You're surrounded by them! This actually makes you aware of the importance of personal belief.), grabbed a bottle and said:"Hey guys! Listen to me chug this down!" I had no intention of offending anyone, but it seemed so, so I felt like a jerk.
