I got followed.
So me and my friends were walking around town, and so we saw three hot guys on bikes. So we waved and then they hung out with us riding slowly behind us and chatting. That was fine. But then a guy in a red shirt came up to us. It didn't feel right so I walked away and the guys started biking so I had to jog and tell them what's going on. Then I get a text from my friend saying;
"Hey did you call me?"
I reply with no and then I see the girls start to run and I start running too.
Turns out it was some chick on her contacts list warning us about a guy in a red shirt following us.

 That's not all. He came back and chased us on his skateboard. Luckily we said we had to go and another group of girls walked by and he went to follow them instead. 
I was crying and freaking out. 
We were followed.
