Neigjbour rarely puts her own bins put, she wait until other people in the atreet jave out theres pit and just goes and distributes her rubbish and recycling between them! She lives on her own so probably doesn’t have enough rubbish to fill the bin so not sure whether she just thinks its pointless putting them out. I have caught her a few times when its been quiet in the street and I’ve pulled up on drive or am going out to the car, either late at night (if anyone had put their bin out the night before) or sometimes early on a morning when theres no-one around. When her hisband was alive he would sometimes come and put his dog food tins in our bin! Not sure whether anyone else in the street has noticed and it doesnt really bother but I just find it rather amusing 
I personally wouldnt have the cheek to do it!
