I can picture exactly what was happening in this photo. My grandmother was standing serenely somewhere, minding her own business, when her grandson, John the artist, came up and startled her with a hug and a kiss on her cheek. It might have be a chilly, rainy day. Why else would she have been wearing a "babushka," as we used to call them. I'm sure she laughed and was pleased with the kiss. My grandma was a good sport, always.
