Even at a tender age of 4, my son is always excited when it's Friday. It is not because it is approaching the weekends or the fact that he knows daddy won't have to work but rather, he seems to look forward to a volunteer job that he gets to participate on some Fridays if he is not sick. He gets to go to different elderly households and deliver meals.
Each Friday, the volunteer meal deliverers gather at a local church to pick up boxes of special meals according to specific dietary constraints. Some folks drink butter milk, some would take skim and then there are the minorities whom would be allowed to drink whole Milk, followed by different meal plan for different diets. So far, my little boy is at least helpful in helping out picking the right kind of milk for the right folks since the milk cartons are in different colors. He becomes more helpful when the actual delivery takes place.
He would YELL out "MEALS on WHEELS" to get attention prior to the knock on the door. Usually folks are already opening the door prior to the knock because they do look forward to a cute 4 year old delivering a meal with a smile and a mischievous grin. He would normally deliver the meal and then ask "what about me? but I am Hungry too." The response is always a grandpa Santa Claus type jolly laugh then a hug followed by a pinch on the cheeks and finally a candy or lollipops. He has become the Every body's Grandchild on Fridays. This does serve two purposes. My son's grandparents are far away in Asia and most of the elderly folks don't have their grandchild's nearby.
