We have had so many moments where we have been blessed with people's kindness, like several years in a row that Christmas was going to be a little on the skimpy side (DH and I both come from large families and we also have 5 children) we received cash in the mail from Santa Claus.( the card was signed Santa Claus and there was no return address) it was always enough that we were able to give our children nice gifts, have a great meal, and enough left over to give a good amount of food to the local Christmas food drive.
To pay it forward, there was a woman that was neighbors with DH while he was growing up, whose children are in school with my children, their house burnt to the ground. Just that week we found ourselves with extra money that was not earmarked for anything in particular (that did NOT happen very often). We decided to put it on a refillable visa card so they could use it for what they needed, clothes, food, fuel, whatever. I don't think they ever realized who gave it to them.
