My neighbours teenage son currently has some friends round (his parents aren't home) and bloody hell they are being noisy! My son is 15 months and currently napping and they have already woken him up once but luckily he went back to sleep. They were out in the garden earlier swearing frequently and loudly! They were blaring music (the teenage son does this when home alone but only loud enough for it to be annoying if you are in the garden most of the time) but that has calmed down for now. Do I put up with it, knock and talk to the son or wait till his parents come home and talk to them? Or go with my original plan of drop kicking?
