Rantings of a Lunatic

So I created an account on Facebook, to make sure that certain parts of my life weren’t intermixing, and it has a feature where it suggests who your friends are. This is pretty cool, because it is pulling up people I haven’t talked to in 4-5 years. Awesome, I should be friends with them, we went to college together, that makes sense. Then, it starts pulling up other people. Like the guy I bought my motorcycle from. How did it pair me up with him? I have talked to him on the phone twice, and I bought a motorcycle from him, none of which facebook should know.
Thats a little creepy Mr. Zuckerberg.
