In my son's (15) PE class they are about to start their swimming unit. He's asked me to write a note to the teacher requesting he be permitted to wear his swim shirt. He usually wears it if we got to the beach or something. But he's not worn it for school swimming before, I think he might be self-conscious because PE is mixed with the girls from year 10.
I have refused to write the note, because the uniform is very clear that boys have to wear swimming shorts or trunks, girls one-piece suits with optional shorts. The school is generally very strict with uniform. Frankly I think it will help him get over his self-consciousness, and it's a reasonable rule because that's a perfectly normal swimming costume for boys, so I don't see any need to get into a fight with the school. But he's protesting that it's unfair and that I'm not supporting his wishes. Am I being unreasonable?
