RE: are you a master of deer hunting?
I used to know everything when I was a teenager my father was dumb.
seems about my 19th birthday I woke up one morning and dad had got a college education over night.
If I ever stop learning may somebody put me 6' under.
Webster's dictionary says,
expert (syn) adept, handy,skillful,clever knowledgeable
(ant) untrained,unskilled,inexperienced.
My father always said,
expert a person who knows a little about nothing important
