By the way, your Mom is great.My Mom would say kind of like"Don't even think about it,please!",though she is great too.
My sister said:"aaa...., Harvard! if you go to Harvard, I am gonna be crazy!"
Guess how I responsed."Oh,my dear sister,I will try my best not to choose HBS in case you are really mad.And if you try your best, you will make it to go Harvard!"
