Hey TB - I'm not 'pushing it' but only for clarification, if you call those shelters I'll bet if you ask them if they need help with dog walking they'd be happy to have you anytime day or night. I didn't know this about shelters until I called.
I am training now to work at our local women's center (domestic and sexual abuse). There is a great need for assistance with the kids...always. It may also help to keep you sober -- being accountable to the kids and all. Y'know?
