Where Do People Get Their Nerve

Was at the nationals this past weekend and had a great time. Saturday cruise in Heath was nuts but still a great time. Then on Sunday sitting with freinds BS"ing and getting rady to leave and this guy comes up to me and wants to talk about the black chrome wheels on the valiant. As we are talking this other guy comes up and buts into our talk to tell me how much he loves the car, how he is building one, wants his to sit just like mine and so on. Then I get the "But" I dont like the big cap gm ignition you are running, and wants to know how I could not run Petronix its only one wire. I tied to explain my choice till one of my buddies yelled out for him to get F""""" and to leave.
I build my cars for me, if people like my cars thats great. I enjoy talking to people and the car has gotten a lot of attention but sometimes people are just nuts.

Been there, and i just ignore them. Last time i had a guy giving me praise for my duster, then literally started chanting "the 904 is junk" when i told him what i had for a tranny.

I spent the rest of my time in the lanes talking with the guys racing hondas, because they just wanted to talk about building cars.
