@bouncepaw this is a very interesting post as it raises a multitude of philosophical questions.
You've bitten everyone you could today? Truly, you've reached the potential number of people you COULD have bitten? This is where the interpretation comes into place. Maybe you can't bite everyone, but rather have some sort of moral compass that only allows you to bite certain kind of people, but the way I see it every person that crossed your path today was bitten. Not only that, but in order to bite everyone you could, you must've gone out of your way to find people to bite, so I'd assume. Otherwise you didn't bite everyone you could as you didn't maximize your potential here.
I'm very interested in the number of people you bote (yes, I'm inventing this as the past tense of bite).
@ErikUden actually, no, I didn't bite every person I could physically reach. I did follow the moral compass and bote only 3 people. The idea of biting strangers sounds alien to me, to be honest. But maybe I should investigate this topic more? Perhaps I'll become a better biter this way.
