Good moms get all their kids' school supplies weeks before school starts so that they can send everything in on the first day.
Great moms drive to Walgreens at 9pm the night before the first day of school when they realize that they bought folders WITH prongs instead of folders WITHOUT prongs, so that they can send the right school supplies on the first day.
At least, that's how I see it.
PS. I bought myself some Zotz while I was there, scrounging to find the last yellow folder, so I'm all good.
