['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.
My nephew was racing around our house, and fell head first into the corner of a bookcase.  There was a ton of blood and I had to take him to the ER.  Luckily, it was better than it looked and it wasn't a huge deal.
