Gardening

Spent most of the day in the garden, hacking back the overflow from a couple of next door's plants. It has let a lot more light in but it has highlighted just how much their fence is leaning into my garden. Do I go and speak to them about it? I'm not sure they will be aware of it because I think it's hidden from their view by all the shrubs in front of it. I haven't met them before so it might be a good time to introduce myself.
