unlimited media: it's not always like this, but sometimes it is

Jack, age 4, yells to me as I'm closing a drawer:  "I WANT that!!"

I look around.  There is his DS with a little cartridge next to it.  He must be talking about that.  I pick up the cartridge and hand it to him.  "No! Do it with me!" he says.

Okay.  Maybe he needs help. I pick up the cartridge and begin to insert it into the DS.  "Noooo!  Thaaaaat!"  He's pointing to the aleph-beis flash cards.
