Mom and dad are gone all the time, too. When they are home, they're always shouting at us because they seem to be in such a hurry. Everybody wanted to share what was going on in their lives with the rest of the family. Afterward, everyone cleaned off the table and did the dishes. Mealtime at our house is a completely different story.
Mom calls the children to come to the table, but they come dragging in one at a time.
We're almost never all at the table when dad blesses the food. He says the blessing when he sits down at the table whether or not anyone else is there. We all eat in a hurry. Then everyone scatters to avoid doing the dishes. I sometimes think that if we could have family home evening it would help.
