I don't have a problem with people telling a story and embelishing the truth. Little to spice it up, its when thry flat out lie to u to make themselves out to be something they're not or when they do it just to do it.
A kid I went to school with was the worst about it. He'd lie out of habit."dude, I just had the best cheeseburger for lunch". Bullshit. I just ate lunch with u and you had pizza
