A friend of mine has a brother whose b-day is the same as mine, as is her father's

So she has no trouble remembering when mine is! I was SUPPOSED to be born on or around June 25 (my uncle's b-day), but instead I got into a big hurry (to this day I'm still trying to figure out WHY *L*) and was born three days after my aunt's birthday. Go figure! And just for spite, my aunt had my cousin in August, four days before my mom's b-day! Anyway, happy b-day early to you, too!
