I will share the first time ever I made funny faces at random people.
It happened back in summer of 2016, after my 10th grade board exams got over and we went to our native Siliguri and Falakata for summer vacations. It happened during the starting of April 2016 and that was the day when were gonna return to our city Bangalore so in 2016 I didn't really make funny faces in Falakata. It was around 1 pm and I was sitting on the 1st floor balcony in my grandpa's house in Siliguri. I was feeling really bored but then suddenly I saw 2 guys going somewhere in a cycle rickshaw. They were college students who looked in the 18-20 age range and I was only 15 and in vacation mood so I decided have some fun. They both were looking around and even looked once at our balcony too. Thats when I showed one of them my tongue and made funny faces at him. He was full surprised and immediately told his other friend about it and both were continuously turning behind to see me and were full surprised but they were in a moving rickshaw so they couldn't do much other than looking behind at me. I was a bit nervous at first as it was the first time I made funny faces like that but later laughed hard hahaha. I still laugh remembering that moment. I imagine that guy probably said "oi dekh oi sele ta na amader zeebh dekhasse" to his friend which means "hey look that boy is showing us tongue" in Bengali. The way it is said in Bengali sounds really funny hahahaha.
