Mrs. Bird was just a tiny girl when her dad started taking her and her brother fishing. Her dad was a patient man. Translation: he could sit in a boat all day, waiting for the mountain lake trout to bite. Sitting in a boat all day, with a lunch and canteens of water and, if they were lucky, some bottles of pop, made for some interesting bathroom needs. Mrs. Bird's dad and brother were equipped for easy disposal of full bladders. "Turn around," they would say to her and in half a minute, "Okay, you can turn back."
But for a little girl it was a different situation. That is why her Dad took two cans in the boat. One was full of worms and the other was empty. Mrs. Bird learned to go, even in the middle of Fish Lake.
Mrs. Bird's learned nonchalance about bathroom duties in odd places at an early age. This will help you to understand future posts about Mrs. Bird.
