Funny moment of the day:

I'm taking my friend Weijing to the airport tonight to fly home to Mexico City for the holidays.

She needs to take a shower first, so I hand her a towel and she goes in the bathroom.
The water goes on, the water goes off, then on again...

She comes out in a towel and says,

"Um, is there hot water?"
"Of course there is..."
"Well I turned on the C knob, for Caliente, and it was cold, then the other one was cold too."
::pause::
"Honey, C is for Cold.... "

"aaaaaaaah!"

Gotta love her.
