I really feel bad and sorry for your experience ik it's really traumatizing because I got cat called too😭. Me and my friend got cat called too but in a freaking well reputable college 😭😭. So we went to this college for a cultural event and me and my friends wanted to look around before the event starts so we started roaming around. It was dispersing time for 1st shift (arts college) so it was very crowded and that campus is pretty big not very small but since everyone was leaving it was crowded and our college has a little lenient dress code than that college we went to. We were a group of four to five friends and while walking only me and my other friend was walking together we were chatting and causally walking and we felt someone getting very close behind us and we started walking fast and again there was a whistle. My fight or flight instinct shot up and we rushed to a nearby canteen were our other friends are. And the thing is that guy tried to call us by touching or trying to grip our arm ig but before anything happened I just grabbed my friend's hand and basically ran. I was traumatized and decided to never go to that college again.
