How about: "You've provided opportunities and experiences for your child that other parents are not able to provide." (Code for pushy parent or your kid might not actually be that smart.)

Also, "I haven't been able to work with my child outside of school." (Code for my kid is as smart as yours but I dont' hothouse mine.)

Both of these get my goat because they come from people who don't know that my kids learn with almost no help from me!

She thought she could, so she did.
