I will share something very funny which happened with me. Do you also feel it was funny?
Back in Dec 2019, we went to our native Siliguri to attend my cousin's(dad's sister's daughter) wedding. One day I was sitting on our 1st floor balcony and looking at the streets. I was 18 almost 19 but still was making funny faces at random 18-early 20s aged guys there for fun and passing some time. Whenever I go to Siliguri or Falakata, I forget my age and become full crazy and childish as I will be in vacation mood. As usual that day too I showed tongue and made funny faces at a guy in his early 20s who was going somewhere on his bicycle. But surprisingly he too smiled at me and showed me middle finger. I was laughing hard but it wasn't over yet. Again while returning on his bicycle after around 15 minutes he again smiled at me and showed me middle finger and went. I didn't expect that at all honestly but it was fun hahahah.
