My nephew was racing around our house, like he has a million times before, and someone took a bad fall into the corner of a bookcase.  I had to take him to the ER.
Ouch! Kids have a tendency to learn things the hard way. Was he okay?
Yes, luckily it looked much worse than it actually was!
That's good! My son is always running into stuff! He needs bubblewrap to keep him safe.
