When I first met my husband's huge family (parents,11 brothers and sisters, plus spouses, aunts and uncles) it was at a picnic. Halfway through his father, came up to me and said, "You know you don't have to smile all the time."
My father always told me that when I smiled it was like I'd turned a light on. He wanted me to smile all the time.
There are people who think I smile too much and people who tell me I should smile more. I glare at them all.
