Sorry, I don't have time to dig up old blasts from the past so I'll leave you with a visual.
Picture it - a three year-old boy that has been fighting a cold for about 4 days. You know, the nice snotty, boogery nose kind of cold. Got that in your head?
Now, picture yourself walking down into your family room and seeing said three year-old on the couch laying on his back.
Now, picture big brother sticking his finger up the three-year old's nose trying to "clean things out so that he can breathe."
I guess they do love each other.
