I've been thinking about this lately and my thoughts resonate with yours. My situation has amplified since moving to London a little over a year ago, where I had no friends or family. I've been wanting to go back to a simpler style of friendships like when we were younger.

At the same time I've also missed sports. My solution was to get back into skateboarding. I haven't skated in ten years but you'd be surprised by your muscle memory. I got all the gear and headed to the nearest skatepark and was quickly approached by the local skaters. I met a lot of great people and skated with them all evening. Haven't had so much fun in a while. Can't wait to go back.
