A very wise man once said - Don't accept or reject everything. Listen, test, reflect and then practise - . Of course he was referring to the teachings of his faith but I think it applies to most things in life.
I'm so glad you did not voice your opinions to the senior or , having met many like him, he would have given you a blistering look and in the most imperious of voice say 'Young man, I have taken more salt than you have of rice.' (BTW This is a be-all and end-all Chinese quote of elders to put young people in their place) And that would surely cause all the leaves to fall off your bulbos!
