I am a middle child. My role in the Road Rambler on family trips was to confine myself to the “diaper”, the narrow strip between the two backseats. This required I contort myself to avoid touching my brother or sister for five hours. My family trip duties en route also included, optimally, not peeing my pants and not reporting their bad behavior.
In adult life, when my husband flumps a limb to my side of the bed I have a violent reaction. The sanctity, the dignity, of my small space must not be violated.
Thankfully, I have overcome the tendency to pee my pants.
