There’s a social “block and tackle” that we call a smile. An electric lineman once came in contact with a live wire, and the left side of his face was paralyzed. The jury, in considering the damages, asked him to smile, but he could only smile on one side of his face; they subsequently awarded him $100,000 damages. If half a smile is worth so much and yet it costs nothing at all, then we certainly ought to have it in our “social tool chest” and keep it in good working order, ready for constant use. It’s worth a million dollars and yet it doesn’t cost a cent. However, we should also remember that one who doesn’t smile may not be any better off than one who can’t smile.
