There's a footpath down the side of our property, with a garden at the back that is fenced off. We are friendly with our neighbours and socialise regularly. One neighbour walked into our garden last week to look at our chicks. She didn't ask and didn't know she'd been seen, although she knew that DP was at home. Her adult son had a friend to stay recently and the only time they went out was to walk down our path and peer over the fence. This evening a different neighbour brought his young daughter into the garden to look at the chicks. I wouldn't walk into their gardens without asking and I feel that they are being very rude. I'm tempted to put a lock on the gate but this makes it difficult for DD to look after her pets. What would you do?
