conspiracy

I think there is some sort of arrangement between ALL of the companies that make pants for boys. They do something to make the left knee area weaker than any other area so that it wears out, creates a hole and requires a mother to purchase new pants frequently. Case in point... 3 different brands/kinds of pants, 3 holes, all left knee. poor boy, he currently only has 1 pair of play pants at the moment. Do I dare allow him to wear his church/dress pants around the house?!
