yeah I do understand the concept and agree with it, but put the coffee cup in the dark corner of the hallway celing where I travel everyday, chances are I will never notice it.....
In my neck of the woods the deer dont seem to look to much in the trees for predators....I guess they havent caught on yet
And I shure as heck dont look for my coffe cup on the celing either...lol...friendly ribbing thats all
Just do what makes you feel confident...
