Christmas is no fun when you're poor. Twenty years ago I was a young, (struggle), substitute(替补) teacher whose calls into work had been few.Money was tight, bills were due my wife and I couldn't even afford to get Christmas gifts for each other.The only gifts we could get for our children were a few soft toys that I had found (sell)at half price in the supermarket.I opened the door and brought in the gifts I (hide) in our old car's trunk.Then I handed to my son and daughter.I watched with a sad smile as they did their best to tear off the wrapping paper.As they pulled out their toys, though, I noticed their faces lit up and jumped up and down.My daughter (happy) hugged her toy and then hugged her Mom and me as well.I laughed as I watched my children play with their toys _ hours, and thanked God for the (great) happiness I had ever been given.Till today I still treasure gift of pure love that my son and daughter gave me that day.
