My brother is an ENFJ.
Growing up, his extroversion was hard as shit to deal with. That and we're only 14 months apart. Crazy dynamic. He partied a lot and got in fights often. Now that he's older he's more into hanging out with his girlfriend and working on his jeep, playing video games, etc. So when we were teenagers we didn't really spend a lot of time in each other's company. We're so unbelievably different but so similar. It's a weird family dynamic.
