What is your biggest pet peeve?

My biggest pet peeve is when people lie. I hate lie rs and i especially hate when people tell this big extravagant stories and they end up not being true. I don't know why people lie all i know is that it gets under my skin when they do it. What i don't understand about people who lie is that they always get caught in their lie later on and they want you to feel bad for them for whatever reason. I just choose not to be around people that are like that. If i know that someone is a lier when we first meet i don't try to be friends with them, and if someone i already knew turns out to be a lier i just try to keep my distance from them.
