I agree with fairylea wise words.i hate bins they really make me cringe. My main bin is in a cupboard under the sink.
My husband allowed little uns to have bins for waste paper they doodle a lot, and snotty tissues. But muggins cleans them all out. If he was out the picture they wouldn't have them.
if she were my daughter i wouldn't let her go to sleep until she wrapped it up then disposed of it in the main bin in the house. if she felt her life was unbearable because of some basic hygiene I'd show her the door. no excuse at her age I fully sympathise.
I don't agree with the comment she's an adult, if she's an adult and responsible she should act her age and not have to be told about basic hygiene matters. If she wants to live like a slob she should get her own house and do that. The reality is she wouldn't do that in her own home. I know I have a herd of brothers they don't pick up a finger in my parents home despite living there into their thirties? They won't put any money into the home do it up for parents, who can no longer afford to. Yet they live rent free. have food cooked for them , by women folk of house, they even get laundry done. When two of them got married, miracle of miracles they got brand new kitchen, bathroom, everything. They somehow got money to do their place up but forget the parents who cares right we used and abused them. their place is not a pig sty, but they were happy to live like pigs in parents house?
I think his girl is doing the same disrespecting her parents.
I have a brother 23 yrs old, staying with me he is a little messy and wouldn't initially clean his room or make his bed, forget doing clean sheets regular. I want going to have him treat my place like her did my parental home, so I nagged just to annoy him. then I said you must tidy your room and clean one of the bathrooms in my house once a week or you'll have to go back to dads I can't look after you. I do everything, he gets to live rent free, have all meals cooked for him. So he was moody with me for a few weeks but I remind him if he doesn't do it, and he has it done before the weekend is over. If it means nagging to get the chore done do it, at least you're not tolerating the disgusting behaviour in YOUR HOME. Getting him to cook is a work in progress but that's his choice he won't be here forever if he doesn't wish to learn he'll never taste my mothers home cooking again, she's passed away.
My son was six when he decided he'd eat upstairs sneakily and dispose of half eaten fruit in his bin. I warned him I hate cleaning bins with rotting food. Then I got his pretty little bin that he had saved up for and disposed of it outside. several months later he has learnt his lesson new cool bin, only waste paper in it.
If you see her get in a new bin, take if off her. Say no bin allowed in her room unless her sanitary stuff is wrapped and put in main bin rather than bedroom. I think it's disgusting too.
