I wonder if the fact that I don't really know what it would mean to think about somebody in terms of single/cohabiting/parent/childfree etc shows some fundamental flaw in me. Not just T, but people I actually know as well. Sometimes people tell me gossip about mutual friends who have entered into a relationship or broken up or had children, and I am really bad at remembering that stuff. (Kids especially.) To me, a person's relationship status is not part of their identity, and it is (almost) never interesting to me. I guess that makes me messed up.
