She left her shoes in the living room so I'm going to toss them in the trash.
Why would you want to do something like that? Sounds kind of rude to me.
I'm very annoyed that she kept them there longer then she should.
Someone leaves their shoes in the living room and you want to throw them away, I have no idea why anyone would do that. The shoes might have cost a lot of money, you could be taken to court for the damage or loss. Ignore the shoes, people leave them around all the time.
You guys should all make your shoes dirty so that I can put them in a trash bin.
Why would you throw away shoes that are simply just dirty? You should clean them instead, it would be a much nicer thing to do and you wouldn't be destroying someone's belongings.
