D is for Drum.

Here's a picture of Clara playing with some vintage toys. The TOMY typewriter was mine when I was little. The typewriter actually advances and dings when you reach the end. When you push it to return it advances to the next letter. Clara is learning valuable skills with a manual typewriter that will come in handy when the technology grid shuts down in some future apocalypse where our Ipads no longer work. Note the wind-up Fisher Price Clock radio in the background. Sure, that toy only plays Hickory Dickory Dock but Clara will know how to hand-crank her portable radio when the zombies come.
