My dad is doing great after his knee replacement. He's doing really well with his rehab, and when I offered to get things for him, he said that he needed to get up and do things himself, a shocking turn of events.

He also let me give him a subcutaneous injection of lovenox, a medication to help prevent blood clots. It was the first shot I have administered to a human. I was a bit nervous, but it was nice to know that my first injection would be given to someone who wasn't allowed to hate me for it.

Me: Do you mind if I post a picture of your knee?
Dad: No, go ahead. Do you want my trademark? (referring to his lack of an index finger)
Me: Uh, sure. Bonus.
