Someone once asked...
Someone answered with kindness...
Develop a humorous state of mind. Imagine his head exploding.
Another soul answered...
Is it worth spending your life trying to fix it? Then fix it. If not, go elsewhere.
Another soul answered...
quit. even if you feel your concerns were not voiced or taken into account, you should quit. this is life. quitting in such a scenario always is the best choice you could make, objectively. even if you will be judged for it. another work opportunity is probably waiting somehow on your action. let your actions speak where words don't.
