Yeah, I am having a 5 closest friends, 20 regular friends and around 500 acquaintances, according to my facebook statistics.
Choosing a closest friend is one of the most different things, because unlike the other experience where you can learn from the others, here you will have to have a personal experience. When I was kid, I must admit, I was having a problem with choosing a real friend. Most of my attempts didn't bring my true friends. But, how the year passes I was having a different kind of experience with a different kind of people.
After I learn the lesson, today I have reach the number of 5 closest friend. I have 3 guys and 2 girls. Even if I don't believe in friendship between male and female, I am able to bee friend with them, because I learn how to control my feelings, but I am not sure about then.
