They're going on a trip... and I have to stay with Guest for a month? With that jerk??
Sigh... Just being in the same house is annoying enough, but staying alone together for a whole month...? Ugh, seriously, so annoying. When we were kids... well, we even slept in the same bed, but now he's so grown up it's just gross, seriously.
Damn it... I hate this so much.
