stalked or stalker

A stalker like killing stalking? o_o I get chillz over my body just thinking about stalking lol
Once me and my friends were at town waiting for the bus, it was kinda late at night, so we were few ppl at the bus station, after a little while a man come to us saying ''oh my, why are you girls out at this night?'' and didn't reaspons, the man started blabling about how he saw us when we were in the shop and wanted to talk to us. We tried to be polite since he was older than us, so we said ''Yeah we know what the time is, so thank you for telling us to be careful'' after the man walked back and went in to a shop near there, so one of my friend wondered if he was drunk, so two of us ran after him and he saw us, and the other two stayed back to wait. after we got in the shop, we slowly walked normal and looked around to act we're going to buy something. It was creepy as shit but lucky thou the bus came and we'd to run back quick to catch it, as we were heading back, we see the man running behind us. We run fast, and got into the bus, and the man was taking the same bus ...

Since that day, i stop taking the bus at night tho ╥﹏╥
