Hostess with the Mostest?

Two of my classmates were hosting an end-of-year house-colding party tonight. The party was called for 7pm so I dutifully showed up at 9pm with drinks in hand. I called up but no one answered. I figured they must be on the phone. After following a stranger into the building, I went up to the girls' apartment and knocked on the door. No answer. I figured the music must be so loud that they couldn't hear me. So I banged louder and eventually went back downstairs to sort out what to do. At this point I ran into some more of my classmates and they joined in my perplexity of the situation. None of us had thought to bring either of the girls' cellphone numbers so without further information we eventually decided that for some reason or another the hostesses were simply not home... and decided that shouldn't stop us from enjoying ourselves, and so the drinking began in the hallway on the fourth floor.

The hostesses did eventually show up and were quite apologetic.. so all is forgiven.
