@futurebird @jcastroarnaud @funkula I loved this story! Did your brother eventually let you join his games, or you kept playing with your friends?
My brother is 9 years younger than me, and my sister 18 years younger and I got them to play as soon as they wanted. I was not around often while they were growing up, and they ended up GMing for other friends etc, but every time I went home I made a point to have at least an evening to play a one shot with them, for years.
Now we play online.
