DD is a bad dresser in general - usually takes her over 30 minutes to get dressed for school of a morning, but with a little encouragement, job's done.
She came home from school this afternoon without her jumper (not unusual, happens several times a week), but also without her pinafore. So, yes, she came home from school with only her shirt and tights on.
Apparently they had gym this afternoon, but had time back in the classroom afterwards and before coming home. She thinks she left it on the back of her chair.
AIBU to expect that the teacher should probably have noticed a half-naked six year old leaving the classroom today?
