Long Night Sleep

Yesterday i came home from work around 445pm. By the time 530pm came around i was REALLY tired. I set my alaram on my cell phone for 730pm, i have classes at 8pm. well, the next thing i know i wake up to my alaram at 5am for work. So pretty much, i gota 11 & 1/2hrs. of sleep and it felt great. But i also missed my class... oh well..
