So, Mark with his autism: 

    …..he covers his ears a lot...like when sensory things are bothering him….when he doesn't like or understand a situation, or something startles him…..(or the sirens in town go off..)...or people laugh hysterically and just aren’t stopping…..or like today, in the grocery store (drawing the attention of every one throughout the store), when "Shake Your Booty" by KC & the Sunshine Band comes on over the speakers ....The checker finally says...”ya know, I don't like this song either “...

…oh the moments…..
