snakes

Dear Wally,

I was told that copperhead snakes, which we have around here, always travel in pairs with one copperhead following behind the first, and that if I see one on the trail, I should not move until the second one passes. What do you think?

--Concerned.

Dear Concerned,

But what if you come across the second one first? Could be a long wait for the next pair to come along, don’t you think? I’d keep moving. Fast.

--Wally
