My sis is 42 and I am 23. We're both recently divorced and moved in together to help each other out. My sister loves to be the center of attention, where I am a more private secluded person. Recently my new boyfriend was over to pick me up so we could get some parts for his muscle car (a hobby he and I both enjoy). My sister had just gotten out of the shower and was barely wrapped up in a towel and decided to come stand in the kitchen and talk to us. My boyfriend was clearly uncomfortable with this... as was I. I didn't know what to say! I was in total shock that she would even go that far to be noticed! I don't want to hurt her feelings or cause any major conflict cause I know she's going through alot, but wow this is pretty extreme. I don't mind her usual habits of being the center of attention: changing conversation subjects to her liking, inviting herself to things, always trying to get me to talk about my daily business or plans, etc. What do I do?
