I think this is the way most parents handle the parent statement–as one more opportunity to check off some imaginary boxes. No offense, but I think this is also the most common and done-to-death approach. It certainly doesn’t hurt the application, but unless it’s done in some completely new, genuine, and refreshing way (and I can’t fathom what that would be at the moment), it will be common/boring at best, cringeworthy at worst.
Just say what you really like about your kid. How about:
I’m delighted when he grabs my hand at the mall, or (sort of) makes his bed when I haven’t nagged him, or doesn’t (obviously) eye-roll if I blow his cool with a hug in front of his friends. I’m delighted that I know he loves me and his dad and sometimes actually shows it. We think he’s a keeper.
And let it go at that? Just don’t overthink these responses. Unless you come off as a nut job, these statements will not be the reason for your child’s admission or rejection. Why not have a bit of fun?
