When was the time an experience that you had came in handy in a most unlikely way?

I was voted in on the board for our area chapter of Habitat for Humanity. I had to agree to serve on one of several committees. I chose the “Family nurture and support committee.” I will be working with low income / poor people probably mostly single mothers..
Among other things I need to just evaluate a family and figure out if they really have what it takes to be a home owner.
I’m to help them with a budget.
Other things are involved, but it’s basically calling on my experience during those years of poverty and terror that I went through in the 90s. I never dreamed that experience could come in handy.
