Im sick and i dont want to go to school tomorrow? :/?

Make sure you make yourself look like hell in the morning. Don't comb your hair, wash up, put on makeup (if you're a girl) then tell him you're sick and need to stay home and get well so you don't get sicker and have to miss more school. Hopefully when he sees you looking bad and hears your logic he will let you stay home. Also, if he makes you go just go to the nurses office after first period and have them call your dad, when you talk to him tell him that your 1st period teacher suggested that you go home because she/he could tell you were very sick.
