A friend of mine said, "You always spend time with your juniors, no wonder they like you." Come to think of it, without the effective collision, even the rate of a reaction is slow. I don't see why our relationships within the circles should be exceptionals. Usually, we tend to judge a person by the physical appearance, not to say good-looking or not, but the impression. However, once we got to know that particular person, we might be like, "Hey, he isn't that bad after all," or the other way round. With the right communication that is, two person get to know each other, the bond in between getting stronger and "poof", we have the product of a reaction, friendship. Something like using catalyst in a reaction and increases the rate. If you try befriending with someone, make sure you have the right "catalyst", along with the suitable "temperature" and "pressure". Otherwise, it might not turn out like what you expected. *wink*
