Mark went with me to "my lake".
And, two days later.....
I went with Eric, to "Erics Lake".

I was a kind, courteous, and generous GUEST of "Eric's Lake".
I let him catch more fish. I let him catch the bigger fish.
I was rewared for this courtousness that I showed Eric on "his lake".
My Reward?...The next day I went back to "Erics Lake" by myself and SLAYED EM!

The Moral of this story is.
Mark?
