Taking out the Trash

How is it that I have phone numbers from guys I've met on CL, POF or OKC and I have no idea who they are? 

I don't usually do heavy cleaning or monitoring of who's in my phonebook, but I decided to go through the list to get rid of numbers since I am bored at work. And as I'm going through them (Friends….. Family….. Work…… Who's this?!), I really have a hard time remembering some of the people. Honestly, I doubt I even met some of the people in person. But I did text a lot. So if anything, these people were all texting buddies. I figure I better just clean out my phone now. I have my new "person" and I wanna have things stay drama free. In the event that he gets crazy, psycho, jealous, or any other kind of weird, at least I won't have "John Doe CL" or "Mr. Smith OKC" in my phone to spark a fight later on.
