I'll start....
Yes, I know he is perfectly capable of doing his own room, but today DS2 (13) was away for the day and I was waiting on hospital visiting time as my Mum is very unwell, I needed something to keep me occupied so I decided to do DSs room as a treat.
He usually picks up all his laundry and clears up any rubbish on a Saturday himself as that's his responsibility but as he was away at 9am he didn't have a chance yet. We have a "no food upstairs" rule.
Anyway, apart from the dirty laundry I found:
2 empty juice bottles
1 empty smoothie carton
1 empty milk shake carton
6 empty crisp packets
3 apple cores
a pile of orange peel
1 grape
a pile of sweet wrappers
some bits of popcorn
2 plastic bowls
2 plastic cups
......and a Pringle tube full of urine 
We are going to have to have a talk when he gets home!
