Actually I made two.
I thought when I helped someone that when the time came they would help me if I needed help.
That was my first mistake.
My second mistake?
Thinking that if someone I had helped didn't help me back then the assistance I had given was not valued by them and that I had been no help at all.
When in fact, more likely, I had helped them enough that they were now doing their thing and too busy to look back as they are now helping others.
Actuallu I made no mistake at all.
