My brother and I always got along really well. We played games together non-stop.
As I grew up, I found it difficult to escape into the fictional life of playing games. There are so many real and serious things to focus your time on. School, work, housework, wedding planning, etc.
But you know what's awesome? Instead of launching a new computer game, he researched an old hobby he thought I could participate in also. Then he asked me to play with him!
