The guilty panel is panel three in this Curtis.
Small mistake: using “may” when you mean “might.” “May” implies permission, though it’s become a mild version of “might.” Still, you’re wise to say “might” when that’s what you mean, especially when you’re explaining something.
The big mistake is common among folks who paid some attention in English class. They typical scenario is when some kid says, “Me and Tom want to go fishing.” and the teacher says, “It’s ‘Tom and I want to go fishing’.” The kid gets into the habit of using “I” all the time in compounds even when the compound is the object of a preposition, which we have here. Dad should have said, “…for your mother and me to give…”
So I guess Dad’s report card was about the same as Curtis’.
