My friend shares an apartment with three other girls, lets call them Anne, Kate, Emma, and Julia. Julia's boyfriend didn't find a place to live and decided to move in without him or her consulting Anne, Kate and Emma. They were annoyed but said he could stay there for a week while finding somewhere else to live. He didn't find anywhere else to live and Anne, Kate and Emma confronted Julia about telling him he had to leave. Julia to him and he got mad. He left for a bit, but came back. Anne, Kate & Emma talked again to Julia, and he left for a bit and came back. Now he is living there again and the landlord of the property won't answer when Anne, Kate and Emma call.
