think of your and Peter’s child deciding they want to do ballet so then Peter having to be great at helping his kids with whatever they love, also ends up doing ballet.
Your child is practicing and doing good, so Peter tries to practice with them, ends up being clumsy and even his speed doesn’t save everything falling and your kid is just sitting on the side giggling at daddy, after that Peter joins another class, adult ballet lessons to be good enough to help your kids with theirs

also male ballerinas have super nice bodies? am I the only one who notices that?
And you compliment Peter on it all the time and randomly mention he seems a lot more limber and flexible now, just an offhand comment that makes Peter’s face light up red causing him to trip crashing into a lamp
