Would you ever contact someone on facebook who you aren't technically friends with? She's a friend of a few of my old housemates, who I almost never talk to but am not on bad terms with. She has been around a few times, but I never had a real conversation with her. Last time I saw her was a couple of years ago but she keeps popping into my head. She actually tried talking to me once but I answered a bit awkwardly because I was high.

Is it pathetic of me not to? Or would it be very weird to blindly message someone? Did it once before and got gunned down ya see...
