# It's tradition to document stuff like this poorly...
# Also, a random comment nobody will understand:
#     Class started 2 hours ago, oh, am I late?
#     No, I already graduated
#     And you can live through anything if Magic made it
#     They say I talk with so much emphasis
#     Ooh, they so sensitive
#     Don't ever fix your lips like collagen
#     And say something when you gon' end up apolog'ing
#     Let me know if it's a problem then, aight, man, holla, then
