What a beautiful question that does bring a smile to my face. Just thinking about smiles makes me smile. Truth be told I am uncomfortable with this subject. One day I smile at my roses. The next I frown at them. Smiling to me is a mood and I wish I could keep mine at all times smiling. Alas I am a man of no great discernment. So I will always smile inappropriately to the world as my happiness is contained. Strange this life, everything should make be smile, yet only my particular mood determines when I do.
I discover this an interesting question. Many things bring a smile to my face. This question brought a smile to me. A letter from a friend earlier today brought a smile to me. Watching the neighborhood kids playing earlier today did so. Leaving a place I got a chicken dinner from brought a smile to me. There are more I am sure, but those I know of today.
Question is very cute.Then there is the joy in the face. When I make a picnic with my family, hang out with them, eating with them, every moment with them at all times to Injoy pleasure of my face is formed.
