Is Facebook having 'problems' with how they 'manage' one's 'friend list'?

[Caroline]

For example, I have a Facebook friend(w/c happens to be REALLY MY FRIEND in person but NOT THAT CLOSE i.e.: former high school classmate) and then I just happened to 'learn' that we're not friends anymore(no idea why delete me) and then I just tried an 'experiment' and 'added' that person again AND THAT PERSON ACCEPTED MY FRIEND REQUEST and I was like REALLY BEWILDERED.....I shared/asked this to a close friend and she said that SAME THING HAPPENED TO HER and that 'person'(her friend) who 'deleted her and became friends again in Facebook' said that she DID NOT DELETE HER, there was no such 'activity' happened.....maybe Facebook is having 'problems' or whatsoever with how they're 'managing' one's friend list....!?? O.o :-\

No They are Not Having Any Problems Facebook Does Not Delete People On There Own Either you Deleted Her or She Deleted you By a Mistake
