A lengthy superhero lesson awaits here, if you aren’t sure who "The Flash" is . . .
Jack (running from the living room to the kitchen and back again, holding a "Flash" figurine): "Mommy, I’m Flash. I am soooo fast!"
Me: "Yes, I see that. Really, really fast."
Jack: "Yes, I am so fast. I’m as fast as a small bird!"
A small bird. Hmm. I love that Jack is trying out his prowess with similes. But Superman is faster than a speeding bullet. Poor Flash.
