You Know You're Tired When...

• You are writing an essay and you start typing the words that you hear on the t.v. in the background
• You are listening to the teacher teach and then you black out and wake up and it's a different subject 
• You put on your pants backwards because you don't want to turn on the light in the morning
• You start laughing after you mispronounce a word, without really knowing you mispronounced the word until someone tells you
• You feel your head falling forward or back while doing homework
• You are listening to someone tell you something, but you don't remember them being there and talking to you
• You leave your phone in the refrigerator
• You say you're tired like 30 times every class and 10 billion times a day
