Well, first of all, not trying to break the "coffee mood" but I don't drink coffee. Not because I'm one of those people that says "It's so unhealthy" or something like that. In fact, I'm just 13 so drinking stuff that will make me really wild and annoy my mom is really not an option. If I did drink coffee, I think I wouldn't sleep for about three days because I'm wound up enough already as a person. Ask anyone.
Anyway, back to what I was saying. I'm not sure by what you guys mean by "companion" exactly because some of you wrote about sunlight, sugar, cream. If my coffee companion is a human, it would probably be someone I haven't met yet. I don't think any of my current friends would grow up to be the kind of person with a Starbucks constantly in their hands.
Therefore I guess if I have to choose someone I know now to be my coffee companion, it would actually be two someones, my life companions. I mean if they're life companions, they might as well join me for coffee eventually. So it would be these two guys, my biggest companions in the world!
