She is supposed to be my intelligent child

Of course I think all my children are highly intelligent but......

We are at Grandma's for the holiday. The new attaction at Grandma's house is the rats. She is rat sitting for my children's cousins as they move to a different state. The first and main intructions given to my children regarding the rats were "Don't put your fingers in the cage! The rats WILL bite them" So what does my oldest do instead? Stick her nose right between the bars of the cage...... Needless to say there are now four little pricks right on the tip of her nose.
