Geneva is awful alone

I'm in Geneva on my own this year and have recently returned so therefore didn't have any plans. I decided to go to the lake and watch the fireworks and enjoy my time alone. I am a young female and thought it was possible to have a good time on my own. How wrong was I. I was out walking down to the lake and was approached, followed, screamed at and hooted at. I got to the lake and saw loads of families people having a good time enjoying themselves, the music was great. I thought it would get better... it got worse I again was followed, spoken to, shouted and now touched, grabbed and pushed. I felt so uncomfortable, I would try to ignore it or not respond, or just walk away but I could not be still for 2 minutes. All of this, by the way was completely unsolicited, I made no eye contact I did not smile at anyone nothing to suggest anything in any way whatsoever. In the end I practically speed walked back home as fast as I could. Is it always like this for single women at night? I don't remember it being like this a few years ago.. though I rarely went out alone at night. I am so disappointed, sad and disgusted. Honestly some of those interactions were terrifying. Sometimes it was a whole group. As far as I could tell it seemed to be coming from individuals not native to Switzerland but I could be wrong. Truly ruined my night.. Happy new year everyone..
