Funny how people change

We just celebrated my husband's birthday yesterday. We have this tradition where we take a Patron shot in the morning for our birthday. My husband was huge party type of person in college. Constantly partying, having sex, doing drugs, etc. He was so grumpy about taking this patron shot lmao. I said "Didn't you snort cocaine off a guys dick once?" He goes "I'm old now" and takes the shot and just looks disgusted and said "I'm not having a good time." He ended up going back to bed and I made him breakfast in bed. I feel like I'm more or less the same person I was in my late teens early 20's. Anyone else feel like they are a completely different person then they used to be lol?
