Terra is bad with flirting.

I was on my lunch break at work and this girl comes up to me in the Halloween aisle and started to flirt with me. At first, I looked around to see if someone had put them up to it only to find that we were the only ones there so I kind of shrugged it off and kept looking at the stuff we were selling.
I thought that was the end of seeing this person so I rounded a corner to the next aisle to see what else was there- and she followed me there and tried again while I was looking at the face paints.
…We kind of vaguely talked about Halloween costumes and then I tried slipping back into the first ailse only to have her follow be back there.
I don’t do well with flirting. The last time someone almost asked me out was in Middle school and when he was in the middle of asking me- I kind of shrieked and ran away. So just picture me flailing and running down a hallway, because that’s what happened that time.
This time I tried to keep my cool but every time I rounded a corner, there she was after me. I was about to freak out and run when someone finally came to the section of the store where we were and it was her mom. So I took this as a change to slip off into a different direction only to hear her ask her mom if she knew who I was and what school I went to.
I don’t go to school. I graduated in 2007. 
Yeah- That’s when I booked it.
I don’t do not do well with actual flirting. Like… At all. Jokingly with friends, maybe, but with strangers who are potentially serious?
