Neighbour thinks he is John Lennon

[SootyCat20]

We live in a small block of flats. It's past 2am and upstairs neighbour is playing the bloody guitar (loudly) and singing (badly). Wibu to go and tell them to shut up??

Do it. TNS. Politely but firmly.

I say be sweet and kind. Ask him nicely if he could please delay his concert until daylight. You get more bees with honey than with vinegar.
