We will just pay the price for the mattress. The photos looked like someone had done a full wee on the bed. Right through both sides. It looked an old stain though. I didn't look at the mattress when Ds moved in. It had a cover on. So it may have been there already. I don't know. Lesson learned there. All Ds could say when I said we have to pay was "well that bed needs a new mattress. It was so lumpy" but I have no proof what happened. Ds said his gf spilled hot chocolate on the bed, I could see that, that was a different stain that looked much newer. He split up with the gf almost 2 years ago. The other dad says he's taking the landlord to court. I'm sure he won't though.
Ds is about to board his flight home from USA the reality will hit home soon. University over, holiday over. Now he needs to start job hunting.
@ZandathePanda great to hear about your younger dd completing her A levels.
