I have an upstairs neighbour who keeps watering her plants and the water goes on my balcony. She has so many plants, some even hang over the balcony. One dropped the other day and all the mud was on my door and balcony.
I politely asked her if she could be more careful and sent her a picture and video. Her solution is that she will water the plants at 9pm tonight rather than in the day and she said "it's not against my tenancy. I've checked". Even though I didn't mention it.
I've explained that regardless of whatever time she waters her plants, my balcony should never be wet as a result of this. This would mean I can't leave things on my balcony - remembering it's summer so its still fairly bright at 9pm.
If she continues I'm going to take further action. aibu?
