Not really an AIBU, but more of an eye roll....
I am in Australia and it is a bright, sunny morning. I heard a noise outside while I was taking out the rubbish. I saw a bloke fiddling around with my car door handles. (We park on the street.) I asked what he was doing and he said he’d locked his keys in it. I said that I thought you couldn’t lock the keys in that model, and he replied that he thought he “must have!” as they weren’t in his pocket. I asked him if he’d like me to go inside and get the keys for him and he said “Yes please!”
It took a minute for the penny to drop, but the look on his face was priceless when he realized whose car he was breaking into. He looked at me, swore, then ran away. (I am a terrifying sight at 5’1 in my slippers!)
I have phoned the police who are coming around to finger print the car and check my cctv. (If they catch him, maybe they can also give the guy an IQ test!)
