What's up with the sink?

I can't really explain it, but for some reason, while we were visiting home, Brady started begging to play in the sink. He would sit for hours turning the water on and off, getting soaked, getting stripped down to his diaper, and so on. I, the mean mother, mostly refused to indulge this strange wish of Brady's, but his Aunt Boo and cousin Michelle were happy to give him whatever he wanted (no surprise there!). I tried to make him play outside with the hose, but after stepping on a bee (me, not him) as I went out to play with him, I gave in and let him do what made him happy inside. He's lucky to have so many loving and indulgent family members!
