Facebook Friend Request

So the wierdest thing happen to me the other day and its quite funny to me when I think about it. I know that people get friend request from people they dont know all the time and for the most part you will either accept it and move on or you push ignore cuz you cant figure out who that person is. Well I had had a bad habit in the past by just accepting and adding people just because but over the summer I went through my friend's list and cut everything down by atleast a third because I didnt know them or never speak to them to begin with. So I go on my home page of my facebook and I have two friend request. One from a girl that I dont know but I've seen her on someone else's page before and another from a guy I didnt know and he didnt have a profile pic which indicated that he had just got a facebook account and hadnt set it up all the way. My profile is set to private so you cant see my page without me accepting your friend request. So instead of rejecting them like I normally would I chose to write them a message in their inbox just asking did I know them because sometimes you simply forget a person or never noticed them in class or whatever. The guy responded with his name and a list of reasons of how we knew each other from high school and church and so i was like ok yeah I know him and accepted his friend request. The girl on the other hand chose to get an attitude with me and was like "I was just adding people that went to Ball State but forget it you can just reject my request since you dont add people you dont know!!!!!!" Im staring at the screen like "Are you serious?"
how are you going to get mad and cop an attitude with me and you know that I dont know you...so I responded with an lol and ok cuz I couldnt believe she took it that seriously. Then I wind up seeing the girl last night at late night and she's mugging me and saying thats the girl who didnt want to add me and mumbling things under her breath. Come on now I thought we all graduated from high school that is some petty stuff right there. I just chuckle thinking about it.
