I said bond but I didn’t mean to imply it actually binds people. If two people work at the same place they also have a bond, but that doesn’t mean they get along. Unlike coworkers, family can’t really become not family, but again it doesn’t mean they get along.

The only reason OP wants to talk to someone who shares none of their interests is because that someone is family. There is no reason they’d talk otherwise. I was trying to say they need to have a reason to talk besides being related.
