<human>: Summarize the given text in a few sentences.

So today I was at my local Wal-Greens to pick up some ear plugs, as I was waiting in line I noticed a girl in front of me looked like someone I knew in Middle school. I don't live in the same area I lived when I was in middle school, I live about 60 or 70 miles away. The girl had Black hair with a dyed blonde streak, so when I got back on my computer at home I looked up the girl on facebook. Sure enough She now lives in my area and I checked her pictures and her hair is black with a blonde streak. So I innocently decided to send her a friend request to tell her I saw her at wal greens and to ask how shes been and all that. a few hours went by and she never accepted, I went back to her profile and see that she turned off the ability to send her a friend request, meaning she didn't remember me and was worried that the stranger who was in line behind her found her on facebook shortly after.
