liar

You know the type... Your stuck... They say that they will lend you some item for a time to get you through... then don't... so like a fool you say again: Can you do this favor for a few? They say sure I'll do it... then don't... Then give up cause it now sounds like begging.... It's got to be that they lie to themselves so much they can't tell anymore? Or indifferent to their friends? Is that reason that they do this to... friends?
