Please don't dislike others even though we have good reasons.

Today, I told my friend I'd try to avoid talking with someone that both of us know because he doesn't have a good temper and he drives very fast without patient. I said it without thinking anything at that moment. My friend asked me how I know he didn't have a good temper. I said because he drove a car very fast, and in my opinion, a person who is not patient, s/he doesn't have a good temper as well frequently. I don't disagree what I said so far, but the problem is that even though someone has not a great temper, should I give up to make friend with them? Or I could try to change them.

What I think is that it's not a good idea indeed that giving up to make friends with people who have bad temper. Probably I don't need to change them, and I don't need to think the person too much. I just have to say something with them, but I don't need to expect to have a very nice relationship with them.

What do you think of this? Try to explain your opinions, and leave some messages as well if you would like.
