Jim would most probably forget until Harvey reminded him and he would be out that door so fast non of the other officers would see him
Harvey would forget but remember and would come running to you as fast as he could he would find you on the stairs so he would run up them and then complain the whole way home
Oswald would be in the middle of something and ed would remind him he'd excuse himself and show up at your school with a look on his face that said here I am
Edward would call you to say he was running late and everytime you would sound sad but he would make it up to you some how
