Just got my new social security card, and also noticed that my old one is from 2008. This would've been around the end of high school/start of college for me.
This suggests that one of my parents lost it at some point, I asked them for it, and they had to quickly order a new one and whistle nonchalantly like "here you go, this is totally the same one you've always had".
Also, that I am incredibly unobservant and did not notice this at the time.
