Helpppp!!!😨😨😨

So I was in the bus and there was a creepy woman who just gave me creepy vibes. She was trynna to talk to me and I was like «ok maybe she just look creepy but is nice » so we had a little chat about my studies etc and when I was about to leave she asked for my number and I gave her a fake one. Now I just dont know what to do next time I meet her in the bus. Any suggestion?
