This is a hard question for me to answer right now as it feels like I don't really have any best friends at the moment. Almost all of my friends have sort of drifted away over the years. There are a couple of friends I'll mention that I'd probably put in that category no matter how much we drift away.

I have one friend who is younger than me who I've practically been friends with since the day she was born. Her dad and mine coached soccer together for at least ten years, coaching my brother's team and then mine. Anyways, she (and her family) practically became like family to me, and their house was practically a second home for me. We would spend our childhood playing silly pretend games where she was a princess and I... was usually the bad guy. We'd also watch Titan A.E. and Jumanji a lot. They were good times. She was someone I always felt I could talk to all throughout elementary, middle, and high school, and we'd keep in touch while I was in college as well. The past couple of years, though, she has slowly answered any phone calls/texts/messages less and less to the point where I don't think I've had a real conversation with her for about a year now. This was even the first year she didn't call on my birthday to talk. Anyways, I'm sure we'll catch up again eventually, it's just sad to just not hear from my best friend of 22 years anymore.

I also had some good online friends back on an old forum I used to be on. We all got pretty close over the 7 or so years we all kept in contact, but they just kind of all disappeared too. I still hear from one of them every once in a while, but the closeness we once had definitely doesn't feel present anymore. Anyways, they probably knew me better than most all of my offline friends.

There are some others, but I probably shouldn't write anymore.
