Thing is, I'm fine with the homemade items! Even, to some small extent, the candy. (Although ... hard candy for pre-K kids? Seriously? And the sheer amount some people send in is mind-boggling.)
Last year, both boys took homemade cookies meant to look like conversation hearts to school. (With classmates' names written in royal icing.) This year, DS1 took heart-shaped pink rice crispie treats drizzled with white chocolate to school.
I'm certainly guilty of going over the top a bit myself. (These were meant for the school party, not necessarily to take home, but I'm sure some kids did.)
It's the little plastic stuff ... sometimes baggies of it! ... by which I'm baffled. It's generally the sort of thing that immediately gets broken, often under foot, it seems.
The last thing we need is more clutter.
Maybe that's a double-standard.
