"If you can't commit to relating with basic respect and consideration with everyone and anyone in his system, leave now. Honestly. It doesn't mean you have to like everyone or put up with nasty stuff, but you need to know that you are not befriending a single person. You are befriending a person who is surrounded at all times by other people who are forced to share /their/ body and /their/ life with /him/."

Well-said. The people with whom one shares one's body are one's family, closer than any other family can be. One might not always like one's family, but if one has to live with them, the only way to live in peace is to love them.

Something people seem to forget or not realize is that just because someone's not 'fronting' does not mean he or she can't hear, see and remember everything that goes on. This may vary with different people or at different times, but it's best to assume that everybody can hear everything all the time, and avoid saying negative things to one person about the others.
