Of course you are. You're too cool to care what any of your past associates would think about you... and that's cool!
That's actually one of the lessons I taught my 2 kids (before not being able to see them anymore). The way to be the coolest kid in the school is to not care about what other kids think is cool. And not just pretend like you don't care, actually not care. If you can do that, you win :)
I don't know your kids but I imagine they're pretty bright! And they probably already know that lesson.
As for 45? I've been doing it for several months now. It's okay, but I must say, 43 was really a lot more exciting. :P
Just kidding, what's in a number? Age is really your health. I'm glad you still have a lot of yours!
