For me, two things stand out.
1. My HS girlfriend reached out a couple of weeks ago and we had our first conversation in over 30 years. What a fantastic walk down memory lane.
2. I have a legit excuse to grow out a great 1970s hairdo. It's glorious. I had longish hair to begin with but I haven't had a haircut since December. Drives my wife crazy (in a bad way) when I swing my head quickly to get the bangs out of my eyes. I don't want to ever get it cut again.
