overheard on the subway

Guy One: This week, I had like ten people add me on Facebook and I don't know a single one of them.
Guy Two: I know! Today I wanted to delete Matt, but if I did that I'd have to delete like three other people.
Guy One: (laughing) I just did a cleanup on the weekend, I deleted everyone from my home town!
Guy Two: (admits quietly) I deleted everyone from high school.
Me: lulz.
