Since we don't have any children yet, most of the enjoyment I get out of Mother's Day is from other people's children.
For example, In church today we were sitting on a bench behind a 2-year-old boy. His grandma was sitting next to him and she had a small whiteboard and a marker that she was using to draw pictures that he asked for. She drew a lion, then the batman symbol, and then a glass of juice. As soon as she finished the glass, he bent over and licked it up.
Happy Mother's Day!
