Wish more parents were like this.
My brother knew I was gay by 5. I used to listen to him argue with his friends over it when they thought I couldn't hear, but without a frame of reference for the term I didn't really care or attach to the idea. Even when other kids in school started calling me related terms I didn't process them as having an actual meaning beyond being an attempt at hurting me, so automatic refutal. Wasn't until almost 15 that I actually stopped to register that, oh, yes, that does actually correlate to how I feel. Oops. That sure put a crinkle in my long terms plans for college, wife, and 2.5 kids. Awkward. Oh well. Now it's college, husbands, 2.5 cats and planned adoption at some point.
