Thank you all for your response! On post #1 I wrote how I learned to drive on an automatic car, my dad's '65 Plymouth. About a year later, I bought my first car, a one year old 1972 Corolla 1200 with a manual transmission; in my mind, I already knew how to drive a manual because I watched my dad all the times when he had one. I took off and never stalled the engine.
My front door neighbor is in his '50s and he has an old manual Civic but he stalls the engine once in a while or I see the car leaping forward; I guess some people never get the hang of it...I've had colleagues/friends that would either shift very roughly or make the car shake while releasing the clutch or slipping the clutch excessively (they should have gotten an automatic instead)
