Lighten up Francis !
If all of our parents acted like this none of us would be driving !
A couple of missed gears is not going to kill your engine, unless maybe he drops it into 1st from 6th at 145 ! But simply lugging the engine a little won't harm a thing. Keep in mind that this man most likely trusted you with the family car (and his life ) when you had absouletly NO driving experience and most likely did it with a smile.
