Some people make me smile. (The word smile should be said slowly with a deep, Southern accent, with an emphasis on the i.) Seeing their bright eyes or hearing their jokes or a short story about nothing important just makes me smile. There's something about them, some perfect quality in their soul that shines through and permeates in me.
These people are quite rare, but when you find them, you have to surround yourself with them, and doing so creates a world of happiness and smiles.
