I feel the more comfortable you are with someone, the less smart you get. Take the instance with my best friend:

Stupidity requires no alcohol with him, and one day we had our 2-men party and needed to set up camp in one of the rooms (the really snug one with the TV and cushions. I told him that it would be so cool if we got the dinner table into the room and he agreed. Using our hands as precision instruments we measured the width of the doorway and the width of the table. The table was wider, our brain cells still intact we thought we could just, in the words of Ross Geller, PiVoT.

Brilliance in place, we pick the table. Things fall off, we decide it’d be better to empty the table beforehand. Yes, now brilliance is in place, we pick the table, tilt it 90 degrees to the side (see illustration attached) and carry it. We are about to pivot, but there’s something blocking the way. I tell him to hang on and check:

There was already a table in the room.
