I Should Know Lyrics

Lyric discussion by SkeezTheGreat 

Cover art for I Should Know lyrics by Dirty Vegas

The song seems to me to be about a man [the singer] telling someone that the world isn't always such a nice place, for he has experienced it first hand. It's not a negative thing, he's just warning that running off from your world and what your world contains isn't the best idea.

or I could be completely wrong :]
