SecondCor521,
Well, you're still on your way to retiring early, and tis better to be able to have a second chance with a partner who may end up being better for you in the end. As for reunions and expectations, who cares what they think? What's important is what you want to do and how you are progressing. Plus, perhaps you might be a bit more approachable now to those who might have thought you intimidating (speaking from experience on that).
What amazed me was that those who had experienced some life setbacks were more human, more friendly and frankly better people - that's what was the nice part of the reunion - I hung out with people who were shocked as it was a change from how I was in high school - I was like you - there was an assumption of what I'd done based on my class standing -while I don't think I've done poorly at all, I just didn't go the route everyone thought I would.
The whole point is to have fun.....at least it is to me - I hope that in the end you don't let those people's supposed opinions stop you from attending - who knows, you just might meet or re-meet some people who can end up being lifelong friends.
