Neighbour is lovely. Single mum, 1DC, they have lived there about 7 years.
DC is now an adult and has recently left home. Neighbour is now home alone.
Neighbour seems to be enjoying her alone time. Mainly late evening. Around my bedtime. Walls are rather thin. She is rather loud.
Any way I can say, Hey neighbour, we can all hear you, without actually saying it?
