Debbie Yost, mom of three daughters, including one with Down's Syndrome, started a great tradition on her blog Three Weddings: Ability Tuesday. On the first Tuesday of each month, she writes about her daughter's ABILITIES, rather than her challenges. What a beautiful idea, I thought.

So, of course, I'm going to steal it. No, not steal it ... pay homage by copying the idea blatantly.

Today is Tuesday and here are 10 things Billy can do much better than I can:

1. Sing. His voice is beautiful, and he adds a soundtrack to everything. His voice is pitch-perfect and he gives equal airtime to music composed by Dvorak (a current favorite) and Elmo (eternal).

2. Keep rhythm. Ask his Kindermusik teacher, Mrs. Jaci: His sense of rhythm is freaky-good. Insanely, we bought him a drum set for Christmas, though he will happily drum away on anything: table, chairs, microwave door, windows!

3. Remember people. It's not names he zeroes in on; it's usually some detail of his first encounter with someone, a detail that they might not even remember themselves. If you had a dog with you the first time he met you, even if it was six months ago and you were just dogsitting, you better be prepared to explain the absence of said canine on each subsequent encounter with the Billster.

4. Remember ANYTHING. Song lyrics, movie dialogue, the complete text of books he's only heard a couple of times. He has a media library in his head that I often wish I could tap into, particularly when someone is boring me (see #8).

5. Get his way with my mother. Where was this push-over when I was growing up?

6. Climbing. He's half mountain goat, half squirrel.

7. Dance with his heart and soul in it. Let me tell ya: The boy puts the “bust” in “bust a move.”

8. Entertain himself when people around him are boring. I wish I had the guts to just completely check out the moment someone starts boring me. And start singing my favorite song loudly in their faces. Or dancing with abandon for no apparent reason. Or pull their cell phone out of their purse and start screaming for them to show me the “Angry Birds game!” Kids are awesome and they don't even know it.

9. Escape from his clothing. Oy vey! Can I say that even though I'm not Jewish? Because the situation warrants it. If you don't believe me, click here for our trials and tribulations with our young Houdini.

10. Make Willow laugh. They have their own language. He only needs to look at her in some inscrutable way and she just falls over in hysterical giggles. She adores him and he can't make a step without her at his heels, just waiting for the next hilarious and fascinating thing her brother will do for her.

"If a man does not keep pace with his companions, perhaps it is because he hears a different drummer. Let him step to the music he hears, however measured or far away." -- Henry David Thoreau
