We are very fortunate to have a holiday home abroad. We have a pool, our NDNs don't. We have let them use our pool when we are not here. They have family visiting atm with three kids, 11, 8 and 6. They asked yesterday if the kids could have a swim as it was so hot. We stupidly said yes, thought they'd be in for an hour or so, no it was 6 hours. They've been back today. Told them that they can't come tomorrow as we want to relax. I like to sunbathe topless and feel that I can't do this with kids about. We've had friends staying and I want a few days to chill now before going home. Told the neighbours that the pool will be free to use Monday onwards, but they said that's no good as their family will have left too by then. I don't want to fall out, as they live here permanently and do keep an eye on our property, but feel like telling them to fuck off.
