Young or old, if you give birth to them, or adopt them they are your kids for life. My daughter is 21 years old, and just called me a little while ago for a ride home. Her boyfriend didn't show up for some reason. This meant that I had to move two vehicles in the driveway (not allowed to park on street). One of the vehicles was a big ass Hertz rental truck that my dh had to rent for work.
You can probably figure out what happened... I get there, and there she is with her boyfriend. I just drove by and waived I was sooo pissed. I mean I was very happy that she was safe, but I am a miserable person at around 11pm. Especially in my PJs.
