Here's a picture of a little homeless man I feed. He started sleeping under my porch steps last winter when it was bitter, bitter cold. When I would come home and start up the driveway, he'd run away. I felt so bad for him being out in the bitter cold. I started leaving food for him. It's taken about 9 months for him to trust me and actually come when I call. He lets me pet him as long as I have nothing in my hands -- anything in my hands (mail, newspaper, watering can) and he runs, so obviously he's been mistreated in the past.
He reminds me very much of my sweet Wendy (Miss Piggy) who passed away two years ago this August.
So I continue to feed Little Homeless Man. He now sleeps on the porch or the back deck. Madeline delights in sitting in a chair by the door and keeping a very sharp eye on him. He politely ignores her.
