How does a day.. go bad?

Haha, I think this is the best topic EVER... How does a day go bad? Some days you know you just wake up and your realllllly tired and that can just set it off! and it seems to me that it's those days where you lack sleep that are the worst. you have mood swings, your irritable.. Most days like this start off being tired and escalate to bad hair. Forgot to do some kind of homework... missing breakfast. Late to class. Boyfriend gets an attitude. lol the list goes on and on. these are just a few examples of how my day can start off badly...
