Me (while writing letter): What are you up to?
Mr. Waffle (typing on computer): Hmm, whatâ€™s that?
Me (patiently): What are you doing on the computer?
Him (vaguely): Computer, what?
Me: Are you booking something, buying something?
Him (stopping typing and waving hands in front of face): Iâ€™m afraid Y chromosone has caused a general protection fault causing this programme to terminate. Would you like to send an error report to the creator?
