I was lucky enough to catch your smile today (Sat. July 18) at Safeway, you (a man) were wearing a blue t-shirt and jeans, I was the dark-skinned girl wearing a blue dress and had a pony tail. I saw you in an aisle, then again at the check-out. I was having an off-day, so it was nice to receive your smile, also I was too shy to smile back for more than 1/2 a second, but wish that I did. Was your smile just friendliness, or perhaps more?
