Sorry to hear.
My sister lives with me and brings in some odd people at times. Her "best friend" was kicked out of her place were she was living and thus they both asked if she could stay with us til she could find somewhere else. A little stay turned into 3+ months and long story of crazy events. It finally blew up last week resulting in my sister missing clothing, perfume and all her money that she needed for her books for some summer semester classes at the college. To top it all of either this girl or one of the people she was letting in at all hours of the night stole my pain medication (which was in my bedroom, not in the open) knowing full well my chronic pain disorder.
Needless to say my husband and I are quite burned with trying to help people and definitely won't be letting anymore strangers in our house.
