I need some perspective on something that happened today. Had a phone call from ds' school. Apparently his best friend was crying coming into school today, and it transpired that it was because on Friday ds (5) put the little boy's hand down the back of his trousers. The school are punishing ds by keeping him at playtime this week.
I was obviously a bit shocked. Ds has never done anything like this before (to my knowledge) I have 2 older dds at the school and they have never been in any kind of trouble. I've talked to ds about it, and he can't say why he did it. He is upset, and we've established that it isn't ok to do this (which I thought he would have known anyway). I've tried asking him but he just keeps saying he doesn't know. I've tried to ask if it was a joke/ did he think it would be funny. I know how the school will be thinking, and I've asked if he's ever had this done to him/ seen anyone else doing it, he says no. The 3 kids are nearly always together out of school and I am pretty sure there is nothing sinister going on, but I just don't understand why he would do this, and he can't tell me
. Having said that "I don't know" is his standard answer for "Why did you kick your sister/ play with mum's things/ kick the ball at the washing?" He is 5. I know it might be difficult for him to articulate thoughts etc, but I wish he could just give me some sort of explanation, but I don't want to be too heavy handed with him, iyswim
I have to speak to his teacher tomorrow. We've had a long talk with ds about privacy and boundaries, but I'm not sure I really want to "punish" him, although I have said no Wii or computer tonight. I'm fine with the school keeping him in, but I'm worried his little friend won't want to be friends with him any more, or that the little friend's mum won't
. They have been friends since nursery. I'm also paranoid the school will think that we abuse him somehow at home 
Can anyone give me some perspective on this, from a school/ parent pov?? Really not sure what I should be doing.
