I'm all for a "fun" day here and there but she's right - these entire weeks of having to dress certain ways on certain days are getting ridiculous. I sure don't miss some of the silly "fun" things one has to do as a public school parent. Or rather that one is often pressured to do. Moms and dads just have enough to do making sure homework is done and the kid shows up on time tomorrow, ok?
I do wish schools would self-limit to one "silly" dress-up day per month. Because it would be a shame to see it all go. But a whole week of something different to wear (often necessitating a purchase) is a bit much. And then too, I remember when my children were in elementary school that there were SEVERAL weeks like this as well as "bring in spare gloves on Monday, extra change on Tuesday" and so on little fundraisers.
