Apologies for a bit of a late reply, but I spoke to him a few more times and it seems to be under control now.
Although, I have another issue I would like a bit of advice with, if possible.
There is a bit of a stench coming from his room, and he is currently away at home for a couple of weeks, so I took a peek in his room, right or wrong, its done now, but the issue is, his room is FULL of ALL the take away packaging, there are stacks and stacks of pizza boxes, bags of take away packaging, drink containers littering the whole room, you can barely see the carpet at all, its terrible, my worry is its a fire hazard, health and safety hazard, and I worry its going to, if it hasn't already attracted pests, even the bed is covered with the packaging.
Opening the door its like a wall of stench!
I've always reminded him of the rubbish and recycling days when we put it out but obviously, he hasn't done any.
Has anyone had to deal with this kind of thing? I really don't know how I should handle this situation.
Cheers
