Have namechanged as this incident is recognisable.
DS (12) very upset last week (in tears which is not like him) following an incident at the after school sports club. He was so late when I came to collect him that I sent someone in to find him. He had been looking for his bag in the change rooms and it had vanished whilst he had been outside doing the club. Phone (cheap £10 PAYG one but with £10 credit on it), books (including school text books and library books) all gone. Also the bag itself which he had chosen at Xmas and had cost £45.
So to begin with I say it might turn up. Seemed an odd thing for someone to steal and nothing else around the room had been taken. I thought it was an accident or a prank.
A week later, after numerous visits to lost property etc, another boy he doesn't know very well says "haven't you found it yet - I hid it behind the bin". So clearly it was a prank. Trouble is, the bag has gone. DS says that whilst he was looking for the bag he had even looked in the bins and they were all totally empty - with new bags inside. We now suspect the cleaner might have treated his bag as rubbish and disposed of it. Tried to speak to cleaners but their English is very poor and they just seemed not to know anything about it.
So, would I be unreasonable to speak to the school and possibly cause trouble for this lad. He has not apologised to DS though I don't think he was being malicious (I cant be sure). DS wants me to speak to the school as he is still upset about losing his things and I think he wants justice! If it were DS who had done this and I found out, I would be offering to contribute towards the lost items - it is going to cost us to replace the books unless school ask the other lad to do this - let along to replace the phone and the bag. I don't know if that is something I would be reasonable to ask for. Maybe I should just ask for a written apology. Or should I just leave it rather than tell tales?
