We ( My maternal grandparents, Tanisha and myself) were traveling to my grandmother's hometown for church and back in the 70's we had to stop on the side of the road to use the restroom. Tanisha said she had to go and we had about another hour to go well once my gramps pulled over and my grandmother got Tanisha out of the car she said " I TRICKED YOU" because she didn't want to go outside.  She held it for the next hour or so. She had to be 4 or 5 yrs old.
