As a kid, my parents wanted A's. And, if I got A's, they wanted them to stay A's.
WBill Jr has the same expectation from me. I don't see a thing wrong with it.
Only thing that I've added, is that if "A's" aren't happening, then I start asking what needs to change to make them happen. (Mom and Dad made me figure it out on my own....) I'm willing to help - for instance, during a tough time in school a couple of years ago, he asked that I get him there a little earlier in the morning, that extra 10-15 minutes to get his stuff together would be a huge help.
Done, and problems resolved.
as a kid, my parents had no expectations of me, as i was a dreaded female child.
I was (am!) pretty smart too, but we were never encouraged.
Just as an aside, they were old school Europeans.
Maybe if we had been boys it would have been different.
