You can't do anything nice for anyone anymore because you don't know what their motives are. I had a young Mexican girl knock on our door at 4 o'clock in the morning a couple of weeks ago. She was crying and said she lived really far away and wanted to go home. My husband was downstairs by that point and she said she had been at a party (Tuesday night/Wednesday morning BTW) and the people had came to the party with left her there. I asked her if she wanted me to call the police and
she wailed that she didn't want that. She said she needed a couple of dollars and would try to catch a bus. We gave her a couple of bucks in change and she was on her way. Her story may have been genuine but I was leary of her motives. No way was I going to have my husband take her home to wherever she lived--she could have claimed anything at that point.
Anyway, I was kind of grateful she came to our door because
she also informed us that our garage door was open--our garage is full of stuff we would rather not have stolen.
