My ex left his phone behind when we attended an appointment for DD.
When I managed to contact him about half an hour later once he'd got home - I suggested that he pick it up from mine about an hour later.
His reply was to ask whether I was travelling by bus!
I took that to mean he would have expected me to be home sooner - AIBU to think that next time, I shouldn't try to help and leave his phone to be nicked?
