I am a Homebody

I am a 47 yr old and I enjoy staying inside and watching movies. I work out during the week as well. My older sister gets upset because I don't go out and drink and gamble with her.(She's an alcoholic) She knows that I will go out with her when I want but I told her that I've already done everything she's doing when I was in my 20s. She got married young & had 4 kids and now she wants to hit the streets but I don't. It's really annoying.
