I'm glad nothing important got messed. Smart doggy!

I was saying that both, yes would have both, but each of them would have more of one than the other, and the more each had would be the one that the other has less of :P So, one would be more Negative, and the other more Positive. As for what needs collaboration. . . How about anything smarter than a frog? So, they can make bugs and small animals on their own, but the larger animals, like cats and otters, need both of us. Not saying we need those animals specifically, just en example of relative size and complexity. 

Also, not sure if you meant it this way, but I will take it as a complement that you say I have a stronger will :P *Teases*
