I think my sisters have done it with their oldest children, as well. It's a nice thing for kids, I think, broadens their world view or some such thing. What do I know, though? I'm just the weird uncle. (I say that in jest, of course.)
That just means you're a good, dedicated mum, in my opinion. Not that I had any doubt about that. Your children are lucky to have you, though.
Sometimes I wonder if I ought to have pursued a more academic or magical career path, but I love being an actor. Besides, it gives me an odd schedule with large blocks of time off for me to pursue other things that interest me, which is always nice. I think part of it was that there were just beginning to be whispers about You-Know-Who returning not long after I left Hogwarts, and my family have strong ties in the Muggle world though both my parents are magical, so it made sense for me to slip away there. Perhaps I should have stuck around and fought, it would have been the honorable thing to do, but I'll be honest in that I've never been much of a fighter. I do hope you won't hold that against me in this new friendship.
Though I will point out that you have more than proved yourself an intelligent and capable witch, so any who would hold your past against you likely aren't the sort you'd want to work with anyway. I do hope you'll find someone to mentor who will be a good fit, though, if it's what you want.
