DS came home from school today not wearing his jumper. Asked him where it was and he sheepishly pulled it out of the bag, the neck has been stretched so much that the stitching has gone - it's ruined. This was a brand new jumper bought at the start of September, we are on a low income as it is and even moreso this month as DH was off work sick, so having to replace it means we will struggle for the rest of the month. DS said another kid had been dragging him around by the neck, I intitally assumed bullying but it turns out it was a friend of his and they were playfighting. I am furious at him for being so thoughtless and even more furious that when I was explaining to him how much it will cost to replace he shrugged and said 'not my problem is it'. My DH seems to think I'm being too hard on DS, that the other boy was more at fault for doing the dragging, whereas I feel DS is equally to blame for allowing it to happen and for his attitude afterwards, and at 13 should be old enough and sensible enough to respect and look after his things. DS is my stepson and DH has hinted before that I want to see the bad in him and am more hard on him than I would be on my own child, whereas I think any parent would be bloody annoyed. This isn't even the first incident we've had this school year, he's also lost a PE top already and got in trouble for rugby tackling a younger kid to the floor 'as a dare', and last year had numerous detentions and tellings off for stupid things. I feel like his attitude stinks and is more than just 'boys will be boys' and am exasperated at my DHs lack of support. Am I really overreacting?
