My body was shivering

In 2016 when i was 15 and in my town Siliguri on my 1st floor balcony i saw 2 college guys who were like 18-20 were going jn cycle rickshaw. They were looking around and i showed them tongue just to make fun of them being silly and they both were looking at me by turning back constantly until they reached far. I was shivering and also laughing. Idk what they would have done if they were on foot
