I can respect that. I can tell you that you actually get very little attention at commencement. You're in a sea of other people dressed exactly the same as you are. You're all seated/standing/walking in a giant group. Unless you are being recognized for some outstanding achievement the most attention you get is when your name is mentioned when being handed a piece of paper. Even then its one name of hundreds or thousands being mentioned that day. Sure there's hundreds or thousands of spectators, but none of them know who you are and are paying any attention to you. They're there for their own person and you being there doesn't even register with them. If you're worried about attention, its nearly the opposite as you're being anonymized in a group.

I am positive the only people that remember my commencements for either of my degrees are me, my (now) wife, and my mom. One other note: at the time, I hadn't counted on how important it was for my mom to see it. In retrospect I understand raising a child is years of hard work and a constant worry about if you're raising your children right. Seeing them graduate would be a great measure that you did well as a parent.

Still, there's no requirement to do it and if thats not for you, thats just fine.
