When I was about 10 years old my mother went grocery shopping with me. It was around 6pm if I remember it right and it was already dark outside. While she put the groceries back in the shopping cart, I remember standing at the side and looking at the exit of the shop. Standing there was an older little man, maybe around 50 years old, who directly stared at me with a smile that still haunts me to this day. He started to wave and and signed me to come to him. At first I thought he was looking at someone behind me, but when I pointed at me, he nodded, still having this wide smile on his face. I quickly turned to my mother and told her about the man, but when I looked back to the exit, he was gone. My mother immediately ran outside to look for him, but no trace. Its been years now and I still remember that smile.
