Have you ever just assumed you weren't eligible for something, crossed it off your list? I know that I do it. I'm too young, weak, busy, clumsy, single, etc...
I was helping with a program to aid local Christian families in becoming foster parents. I didn't have professional training and my Russian wasn't great for dealing with bureaucrats, but I could offer some encouragement and help with spreading the word.
A single woman at a local church was interested in finding out more and going through our training program. I took a packet of information, and prepared to meet with her.
When we met up at her workplace, I was surprised to see that she was about my age...just a working single girl, trying to make ends meet like everybody else.
