I have a sarcastic side.
Actually, I think models have low ass self esteem. They are 100 % dependent on what people think of them in terms of look. I think life is black and wife IMO but many would disagree with me. I'm Italian for sure but unfortunately I cannot be like Joe Pesci in Goodfellas. "If I see you talking to any guys I'll kill ya. *Kisses her cheek*. 
This one too is classic... actually only Italians can make jealousy seem cute and funny.
Jake LaMotta: Did you f**k my wife?
Joey LaMotta: What?
Jake La Motta: Did you f**k my wife?
Joey LaMotta: [pauses] How do you ask me that? I'm your brother and you ask me that? Where do you get you're balls big enough to ask me that?
Jake La Motta: I'm gonna ask you again, did you or didn't you? Just answer the question.
Joey LaMotta: I'm not gonna answer that. It's stupid. It's a sick question and you're a sick f**k and I'm not that sick that I'm gonna answer it. I'm leaving, If Nora calls tell her I went home. You know what you should do? Do a little more f**king and a little less eating, so you don't have to blame it all on me and everybody else, you understand me? You're cracking up! Ya' f**king screw ball ya'!
PS. Not all models have low self-esteem. A lot of them are just in it for the money and don't care about anything else. I think it's more or less what you learn at home, i.e. role models, that drives how you see yourself later in life.
