Hmmm... I don't think there are resources online for requesting a clarification on your original comment, other than asking you.

Honestly I am not sure where you’re going with this question

Trying to gain knowledge, and you've provided something new which I didn't know about, so I thank you.

but it feels like asking pwd to satisfy you that we have different capacities and it doesn’t feel great.

If I may be honest, this struck me as a very strange part of your response. How can people learn or understand if they can't ask for help to learn?

I'm interested to know what would prevent someone with a disability from being able to offer an hour of their time for a service which is within their skillset?

The single parent is a great example of being time-poor, but an example of something they could more easily offer is an hour of babysitting/playdate.
