it is unwise to get only 5 hours of sleep before taking a 2-year old and an 8-year old to the natural history museum because

maybe you'll not have the energy or mental stamina for the "i don't want to wear paaaaaaaants" argument the preceeds leaving the house and end up stuffing the 2-year old in the shorts and carrying his screaming ass to the subway station.

maybe you'll give a total parker-posey-in-dazed-and-confused bitchface to the 12-year old who snottily tells you that the reason the bell rang in the elevator was because you were holding down the "door open" button for too long.

maybe you'll give a slight hip-check to the pushy tourist who tries to bustle past you on your way out of the elevator.

maybe you'll not-so-silently curse out the stupid euro-tourists who walk up the stairways like they had specially reserved them for their own private use instead of staying to the goddamn right, goddamn it.

maybe you'll need to go to bed at 9:30. good night.
