Famous quotes containing the word box:
“If you like to make things out of wood, or sew, or dance, or style people’s hair, or dream up stories and act them out, or play the trumpet, or jump rope, or whatever you really love to do, and you love that in front of your children, that’s going to be a far more important gift than anything you could ever give them wrapped up in a box with ribbons.”
—Fred M. Rogers (20th century)
