The last few days a girl, about 7 years old, and her mum have stopped outside my house, presumably on the walk back from school, and have reached over the railings and picked some flowers from some of my hedges. Today she must have picked about 10 and then dropped them in the street while walking off. Am I being petty to be p’eed off? I don’t want to seem like an ogre and upset a child if it keeps happening, but surely an adult should be teaching the child that this is someone’s property and not encourage it. AIBU?
