This was DS1' 18th at our remote rural cottage. We had gone away for the weekend ; he and his friends were lovely and pretty responsible, so no worries.
One of hois mates arrived at the party very drunk :-(( and immediately fell over. Onto an antique chair I had restored and re-upholstered.. He was a 6ft rugger player so the chair broke. DS spent the rest of his party worried sick what further damage might be done to our property so didn't enjoy it.
When we arrived home the place was not just absolutely spotless. pristine and in perfect order, I could smell all the tiled floors had been washed (most of the house, open plan) This aroused my suspicions.Outside the back door were sacks and sacks (all neatly tied up) of empty bottles and cans. Far more alcohol consumed than we would have expected or wished.
DS apologised for the chair and said he would help me fix it. (well within my capabilities). I replied, no, drunk X who broke it is going to pay for it to be professionally restored. DS then confessed that the entire gang , very hungover, spent the whole of the next day cleaning up to pacify dragon on her return. They meant to take the empties away but forgot. Poor kid, he was so crestfallen and he'd done his best. He then took the empties to the bottle bank.
I got the chair repaired , gave DS the bill and he passed it to friend.
Weeks passed and friend did not pay up. So, I wrote a polite letter to his parents asking for payment for the repair of damage to my property done by their drunken son. They immediately paid up and apologised. Their boy told DS they had given him hell , but he still never bothered to apologise to us and DS never invited him to our house again.
