Santa

Tonight we purchased two gifts to donate to needy children. We chose ornaments off a local giving tree. When we explained to the boys what we were doing, Michael was perplexed. I explained that these children wouldn't be getting many presents from their parents because they don't have a lot of money. Michael replied , "That is what Santa is for. They will still get gifts from him won't they?" I said yes and quickly changed the subject. Any advice in case he brings it up again ? I am afraid my little smarty pants will be questioning me much too soon about Santa.
