Never underestimate a lazy girl living alone

A few hours after the Hotel Alexis closed Sunday, my air mattress was still set up in the corner of the apt. It was annoyingly positioned between the kitchen and the parlor, so I propped it up out of the way rather than putting it away. I realized a few hours later that it has the potential to be there for quite some time. I proposed to Banana that we take bets on how long it would stay; he countered that since I have ultimate control over its position it probably wouldn't be smart to take a bet with me. Two days later though, it's going strong, and I really think my laziness will win out over my desire to win a bet. Therefore, I bring you:
How long will Alexis' air mattress stay out!

The person will the closest guess wins......nothing. But guess anyway. I should probably stay out of it, but I would say either the next party I have or when my dad first comes down. Feel free to steal my choices.
