Well I've been thinking about this one and I know I have done this. I just couldn't remember a specific example. I just realized today that I'm really being stupid, because we're helping someone right now! LOL
We have a friend who is going thru a divorce and need a place to stay. Since she owns/shows 6 Rottweilers, this isn't easy to find, so we're letting her stay with us rent free. Did I mention that we have 6 dogs as well? Good thing we have a 3acre hobby farm.
There's more related to helping animals, but I'm glad I can say I've helped at least one human...
