wow what? I've volunteered in one capacity or another for the last twenty years including with handicapped children, psych patients and inmates (an art program) how would offering to help one of my neighbors out be any different?
Look, when my house burned down my community raised a little over 5 k in two days to help us out along with innumerable donations for household stuff, clothing, gift cards to go DO stuff and about a bazillion offers to watch kids while we dealt with everything.
Nevermind which my neighbors son had to be stopped from running into a 5 alarm fire because he didn't realize we had gotten out safely.
The power was out here for 14 days two years back from a freak snow storm that took down pretty much every power line and most of the utility poles and a shitload of trees. It was like the apocolypse. Think no power, no fuel and no way to travel normal roads. The national guard was deployed because emergency services couldn't get anywhere (I did fine driving across lawns in an awd audi

cuz the truck wouldn't fit anywhere )
Everyone that had chain saws helped cut out trees out of the road, off neighbors houses etc. Everyone with generators, wood stoves and other heat sources helped shelter those that didn't have heat sources..all the restaurants severed free food before it was junk from no power.
I dont see why helping neighbors out with an autistic child would be any different. I have extensive experience and they're my neighbors...why wouldn't I?
