Do you feel it was weird or just funny of me?

It happened back in end of September 2016, when my last 11th grade mid term exams got over and Dussehra vacations were about to start. So after exams got over, when I was near the school car parking area at around 12:30 pm, I saw one of the construction working guy who used to do repair work in school talking with the school security guard. He used to try to scare me and chase me along with 3 other construction workers. Usually I used to run away from them but that day he was alone. He was in his late 20s whereas I was 15-16 and I decided to make fun of him too as he used to enjoy scaring me. So I went towards the car parking area and made funny faces at him showing my tongue and also showed him my fist and ran out of the school gate. He looked at me with full surprise but didn't chase me and the security guard laughed. Then I went home. This gave a funny starting to my Dussehra vacations and whats even more awesome was that after few days we went to Goa for trip.
