I don't exactly have best friends so-to-speak (nor would they be considered "close") but I do have two people at school who I like to talk with whenever I can. We don't do anything outside of school, but they're the closest thing I got.
Well, I met mine at 3/4 years old at a in-home daycare, and we talked to each other a lot in elementary school. Until I moved away in 5th grade. My mom did have her phone number but I think she lost it.
