I still dunno how old my dad is.. nor his birthday... my mom reminds me every year. He doesn't know mine either. I don't care when he forgets, he doesn't care when I forget. Hell, i've forgotten my own birthday a few times.... the first time was in 8th grade and my GF busted in band practice (we had to finish the song after the bell rang) and started going ape shit about it while I was playing fucking "Louise, Louise" on the trombone.
And when they tell me
I just ''oh gosh, I have been thinking you're so much younger/older''
