For some reason I thought that the word "tardy" meant dirty. One time in 3rd grade I was late to school, so my dad was writing a letter to my teacher and I was reading over his shoulder, and when I saw what he wrote, I exclaimed "Why would you say I'm tardy?!" and started checking my sweater for dirt and smoothing down my hair. He told me that it just meant late, but I still insisted that he change the word to "late" not tardy, because I was not dirty!
