We´re all mad here

Today I phoned my son in Vienna, to get some hard-core information about geoinformatics. We needs it, my precious, because your little sister has a paperwork to finish till Monday, I told him. What he told me was that I´d have to wait for enlightenment until the next day. Son was about to prepare a dinner for four. Wiener winks, bacon-wrapped dates and chestnuts, falafel with minted yoghurt. How come he´d been able to pretend for so long to not know how water looks like when it´s boiling?
