I'm eighteen now, and I've had a best friend since we were seven years old. We've never had a class together since fifth grade, we've never been in the same lunch school since ninth grade, and we don't do any of the same school activities, so we rarely see each other.
She's really shy, and I'm quite outgoing, so I have a great group of friends from theatre and chorus, while she doesn't have a lot of other friends. But whenever we spend a day together, we have a twin telepathy that I don't share with anyone else, and we've done everything from going on a three-week European tour together (no one in my family has ever left the country) to dressing up as figures from the French Revolution for school and staying in character all day. We are going to different colleges next year (we tried to apply to the same one, but she didn't get the scholarship she wanted and had to switch) but not too far away from each other.
Because I don't see her very much-- usually only fifteen minutes a day before school-- I also know how it feels to not have 'a best friend' around for the majority of the day (she doesn't have a facebook, I don't have a phone) and I feel like it's important for people to have someone that they share their memories and secrets and insecurities with who understands them better than they understand themselves. If I ONLY had my other friends and not her, I feel like I'd feel lonely.
In my pants, she has burst like the music of angels, the light of the sun! --Marius Pantsmercy
