You are listening to pop music -- After a while you are so busy that you are not sure if you're coming or going anymore.
You are listening to heavy metal -- This is what you feel like after ONE month.
You are listening to hip hop -- You become bloated due to stress, you're gaining weight due to lack of exercise because you are so tired and have so much work to do and, when you do get home, you feel sluggish and suffer from constipation. Your fellow teachers are too cheerful for your liking, the administrators don’t understand a word you say and the walls of your classroom are closing in.
You are listening to GANGSTA RAP -- After more time passes, your eyes start to twitch and you forget what a 'good hair day' feels like as you just fall out of bed and load up on caffeine.
