If you don't lie, you must be an isolationist. Most people in society don't take the truth gracefully 100% of the time. Being courteous to people or even finishing a conversation with those I don't like is lying in my book. So, I lie more in that regard than anything, and I don't like it. If I didn't lie, my business would probably fold.
If you are independently wealthy, I envy you. I'd enjoy telling all idiots I encounter to eat **** and bark at the moon.
