'We are going to be flying at 30,000 ft..'

while i appreciate the pilot's effort to inform us that we will be flying at the abovementioned height, i will always find myself thinking, what should i do with such information? should i be commenting 'well...thank you. that's my favorite height' or should i be screaming in horror and exclaim,' but I so like 16,000 feet better!'

or i should just shut up and pray with all my might to arrive safely at the destination.
