@Ferd – Only if you’re wearing a black and white tallis, the colors of a cow. I’ve seen some more colorful variants, like blue and white, and they weren’t being worn by “rabbits” (my term for so-called “rabbahs”).
Personally, ghj613, my suggestion is, if it helps your concentration but hurts his, perhaps you could try toning down your shockeling a little bit. He’ll see that you’re making a concerted effort to accommodate his preference.
Don’t worry, I’m on your side here.
