When you dont sleep for 4 days,playing metal all hours of the night,regardless of your family sleeping.Then leave your sister voicemails at 4am telling her you love her but she sucks coz she sleeps,and you get annoyed bcoz it feels like someone is rubbing sandpaper on your eyes and its impossible to type,dance,sing, read, and do your hair! And then yes, after 4am you wake your younger brother to praise his genius and make him promise to genetically engineer you 2 extra arms so you can multitask PROPERLY!
