DSS is 15, he stays with us on and off. No set pattern, just comes to us when it suits him, his mum. He recently asked if he could upgrade his X-Box, DH and I agreed he could trade in his old PS and X-box and use his (DH funded) pocket money to bridge the gap but he was short 150 so I gave him the extra cash. He has an X-box at his mum's but it's an older version.
He needed to pick up something for School whilst we were out so DH told him to let himself in to collect what he needed, and to grab any other 'kit' he needed (meaning clothes, it's the word we use, do you need kit washing for school / sport / going out etc) DH went into his room and the bloody x-box is gone. AIBU to think he should have asked if he could take it, and that it needs to be brought back. For one he won't come over if his x-box isn't here and I don't really want it damaged being bringing it backwards and forwards every couple of days. It's not like he can throw it in his bag for school like a pair of trainers or tee.
Or is it DSS's to do with as he pleases?
