Sometimes I wonder why do people need friends, why do we always feel the need to know that there's someone who cares about us, someone to appreciate us, or to tell us what to do with our lives. I think that actually people want friends because they're egocentric and they want to know other persons are interestd in what they're doing, but thery're not always willing to do the same for their friends.
I think having friends requires a lot of time, I mean, real friend, because you need to spend time with them, to share stuff together, and you can't do this all the time. Of course, you have a family, collegues (and they can also be your friends in a certain way), but I think it's different...
