It was fun. We had a good time. Sorry that your pharmacies ran out of what you call "extra-large condoms", but don't worry about it. The residual ŽÐÏŒþÑ (sorry, there's no word for it in your language) radiation that we left behind will cause the genitalia of the males of your species to wither away in a few months anyway. Please use what time you have left on this planet to clean the place up a little so we won't have to do it when we move here for good in 300 years.
