Where Do People Get Their Nerve

I understand about people out in the world at car shows and places giving there thoughts on things, but do not jump in the middle of a conversation and ruddily interrupt a conversation :wack: I am not wanting to build a pavement ponder V8 car, A person can set back and wait/listen before they jump in with a remark like... Scrap that 6 banger and get a real engine!! I can not believe you dun spent all of that cash on that old /6!! :shock:
Hay! I am a grown man and if you think you can tell me what I need to do to My car, don't expect me to even look him in the eyes with a reply:thumblef: some times less is more, even when speaking :hello2:.
The world is made up of many different kinds of people, and they are so full of there self (self absorbed) they don't even need friend's :D I have been there also Sir Thomas.
