Something along the lines of:
So last night at approximately 8pm, the boys were in the den watching TV, and Robbie had been full of beans all day. Somehow, Robbie managed to collapse a TV table onto Alex's head. The unfinished underside edge of the part set up to hold the legs in place clipped Alex's forehead. How he managed to get from the den to the kitchen with only one drop of blood on the carpet when the kitchen floor looked like a bloodbath I'll never know!
So off to the emergency room we went.
For the most part, the cut had stopped bleeding by the time we got to the hospital but I couldn't tell if he was going to need stitches or whether something like a butterfly bandage would do.
TWO stinking hours later (about 10:30pm) the doctor finally comes in and determines derma-glue was the ticket. So, Alex is now sporting a new cut, likely to end up as a new scar, and a patch of purplish glue holding it all together.
The patch of glue should come off by itself in 5 or 6 days.
