Found out my brother is a druggie

I visited my brother in Denver over the holidays, things were going great and it seemed like his life was in great shape. He's got two children the same age as mine (5 and 7) smoking hot wife, good job etc.

We were sitting on his back porch one night drinking some brews, when he takes out a joint and lights it right in front of me. I thought it might just be a cig at first when the smell hit me in the face. He tried to pass it to me and I was like dude wtf.

He laughed and was like "dude quit being a fig" which pissed me off even more because he knows how I feel about gay people (I did touch my friends ballsack in 8th grade)

I have never been so disappointed in my life. I mean this is someone I've always looked up to. I just never would have thought he did drugs
