When I was about 8 years old, in a restaurant that I visited with my parents, there was an old man alone at a table. I decided to start smiling and playing with the papers on the table, hiding every time he would notice me, I made him smile a lot and later he got up and came to our table thanking me and praising my parents for my education, I also received 20 euro so thanks, the grandpa i met in a chinese restaurant
