MacFarlin saw MacGregor leaning on their shared fence; knowing this meant MacGregor wanted to talk, MacFarlin went to the fence...
"Greetings MacGregor, how are things by ye?"
"I have a bone to pick with ya MacFarlin!" he replied.
"Now what might that be?"
"It seems your son has writ his name in the snow on my side of the fence with his urine!"
"Well you know boys, they will be boys."
"That they will friend, but I recognized me daughter's handwriting!!!! "
