Took DS1 (3.10) and DS2 to the park today, DS1 rode his bike and left it 'parked up' to the fence alongside the edge of the park.
As we were leaving, spotted a little girl sat on DS1 bike. Her mum was alongside talking to her, getting herself onto her own bike. As we approached, the girl said "is this your bike?" to DS1 and he said yes. She said "can I ride it?" and I said "actually, we are just leaving and I think DS would like to ride it I'm afraid". Her mum just sort of stood staring at me, making no attempt to encourage her DD off the bike and obviously wanting me to let her go on it.
I know this isn't a major thing by any stretch, but was IBU to have said no? I sort of think that it's property and if my DS got on a bike outside a park, I'd have told him to get off it. If it had been the situation that the girls mum had been saying 'come on, get off the bike, it isn't yours', I probably would have said 'it's okay, have a few minutes on it if you like'. But the fact that the mum so obviously expected me to let her DD on it made me dig my heels in a bit.
So AIBU?
