No doubt she'll start "sunsetting" by Thursday and Mr. Wonderful Rob will Mr. Last Week.
Know what, I think you have it in your head that Thursday is the worst day ever. I know you joke about it, but how about this Thursday you make plans to do your favorite thing (and no, it can't be THAT favorite thing...lol) or buy something that you've wanted for awhile. Make Thursday the best day of the week for Rob and F what it is in terms of all else. You need to kick that habit.
