I have lived in my house for almost 2.5 years . Same as my neighbours. The problem is their daughter and her boyfriend smoke weed. On hot days it comes in my house . I have to close all my doors and windows every time. It smells its awful. Right now my bedroom temperature is 29 . And I'm way to hot to sleep. I can't open the windows because they smoke ur late at night/early hours as well. I can't sleep with the noise of a fan .
I know the answer is to go and knock. But im gutless . I don't want to cause bad feeling , i don't know how they will respond. I have to live here for many years . And I don't want to trigger anything. I'm really bad at confronting people.
