Friends (the ones we supposedly really care about) are really important to our lives, whether we want to admit it or not. However, every person has times when she/he wants to be alone, and usually when you're feeling like that you'd think that you have no need for friends because you're currently feeling fine by yourself. Personally, I'm afraid that if something happens to a friend of mine while I'm at this stage, I'd turn out to be a pretty ungrateful lil' bastard
When I'm normal though, I think that for certain people I'd like to help them, but not to the point of endangering myself, however that can change, since while there is the mood I described in the first paragraph, there is also the opposite mood, in which we might end up doing a whole lot for the people important to us:lol:
(Thankfully I have only around 5 people, so I think I can manage
