i am a horrible history major

i totally didn't realize yesterday was columbus day. i didn't say anything to my classes about how he discovered america and made us who we are today. hell, i didn't even say anything to my classes about how he didn't really discover america, the vikings did, and blame him for smallpox, syphillis outbreaks, slavery, and the fact that we allow richard simmons to wear glitter spandex on tv. what kind of a history teacher am i?
