I just complain of getting something in my eyes. Wet your hair so it looks like you took a shower, and then when he gets home say you got shampoo in your eyes, and it hurt like a bitch. To REALLY beef up the story, get him to go to the store on the way home to get you some visine, cause your eyes hurt like a bitch. OR if you're cool and wear contacts, just say your contacts were acting up and made your eyes red. Whenever I come home I make a point to take them out in front of my mom while complaining of eye trouble, then run to the bathroom and drop a few drops in my eyes and take a shower.
