This week my DD's school is doing this stuff. Wednesday is "twin day". Each day is something and they somehow relate back to books they have read. I wouldn't go out of my way to protest "twin day" but I will admit I was slightly annoyed to see it on the schedule. Especially with young girls I could see it causing unnecessary anxiety. I will ask DD tonight what she wants to do for twin day. Although she is shy and doesn't have a ton of girl friends she is also a very "go on my own" kind of girl.. so I doubt she will care if she doesn't end up coordinating a twin outfit. Actually I think she is having more anxiety about the rainbow day since her grade is assigned to wear green... Friday we had a blue/back-white/gold dress debate about the only green-blue shirt in her closet and verify that could qualify!
