Came home, found DP keys on the outside of the front door. Handed them to him.
Quick discussion, I would gather some money (day before pay day - had to raid piggy banks). Then pop to shop for essentials for tea. He would take DC's to park. Just got back, they have been locked out!
Apparently this is my fault for not 'checking' he had his keys. Just found his mobile in the kitchen also.
AIBU to have to check DP is capable of being an adult and taking the keys (which I had handed him!). He is pissed off with me and I'm not best impressed with him!!
