Do you have any friends?

I wouldn't say I don't have any friends, because I do talk to my sister sometimes and I'm open with her, but I don't let anyone get close enough to me. Considering that this show teaches lessons about friendship, I used to think that I should memorize them all to be a good friend. However, I don't feel the need to have friends. Does anyone else feel the same way? Do you like being alone or not? What do you think is the reason for your position?
