“When our daughter was young, I was a stay–at–home mom and my husband was a teacher, so we didn’t make much money. We shopped at thrift stores and discount supermarkets to save here and there. But, one week money was so tight I couldn’t even buy bread or milk. That day, I checked the mail and someone had sent me $20 with no return address. That was 25 years ago and I still don’t know who sent it to me.”
