Hmmm this is so serious and a pretty rough period in your life, it's really not easy to survive especially in this part of the world, and with financial challenges those families faced you really tried to stick with them for that long before stopping despite them taking their children for shopping and yet not paying you.
I'm glad you're now in a better position, those experiences in a way has a way of shaping our mindset to the right direction if only we can aspire to make a difference.
