And I was born in 1968. Which totally proves he's my real father.
Just in case there was any confusion.
My niece and nephew called him this morning to warble the happy birthday song over the phone. After they were done singing, my niece helpfully identified herself. Just in case he couldn't differentiate them from all the other under-10 singing duos who called. She can be proactive that way.
Now it's my turn: Happy birthday, Dad! I hope you enjoy many, many more.
