Very cavalier Mr. and a life lesson to all.
Maybe if folks make claims against your work just remain quiet,don't prove anything and crawl into a corner it would have been as they wanted.
Other option, go out do your best, transfer those thoughts, ideas,and claims from paper to reality.Then test,test,and test somemore, until perfection all the while recieving not only professional insults but personal attacks as well.I guess if they can't do it it can't be done....right?
This must be just part of the game,I guess.
If it didn't happen like that I will call them a liar .
