Equipment

If you're talking to me about things I know, I'm comfortable in putting in my 2 cents about what I think about something.  

Put me in an environment where I have no clue what you're talking about...well then, you're going to get a big blank stare.  Most car related things...I have no clue whatsoever  

Rack and pinion steering?  Sure...I can tell you that Leonardo Da Vinci actually created that.  Nuts and bolts?  They go somewhere and tighten.  

How about shaft collars?  I'm going to assume it's for a car but I have no idea.  I actually tried to look it up.  Can you still see my blank face?

Hopefully when I chat with people, I actually am not lost too often.  It's not very becoming.
