Sounds corny, but my family.
I like hanging out with friends too, but my family are the ones I’m most comfortable with and who know me the best. Probably it’s because I can make jokes and know that they won’t be misunderstood (usually). Also they’re interested in more of the same subjects, and often other people have no idea what I’m talking about.
I’m lucky to have siblings who both talk to me and are interesting people.
