"Open up and say AAaaaAhhHhh!!!~!~"

I don’t lie about things that would hurt anyone or cheat anyone out of something. I have never considered myself to be someone that lies a lot, I've often thought of myself as someone who can be too honest ( sometimes ). I just embellish about myself all the time. I would never put up with or stay with someone who has lied to me or deceived me but sometimes I just forgive people too easily.

A friend of mine recently found out that somebody has been lying to him about almost everything he / she ( I'm not gonna list out the gender, so guess for yourself ) has ever told him. From basic shits like where he / she graduated, family background, names, photos and shits like that. And pretty much everything in between. And the best thing is, he / she doesn't even seem to feel sorry about it.

I don't know what to do with these type of species, all those lies just made me completely lost my trust and respect for him / her. He / she should be ashamed and embarrassed by what he / she has done. How does one come back from that? How does one make up for such deception? I mean come on man, it's only a yes or no - as simple as that. Why lie?
