I had the most wonderful English/Creative Writing teacher (shout-out to Rose Cullis, also a writer!), but oddly my memory is blanking on poems that we read for school! But I loved looking for poems online. I would copy and paste all my favourites in a Word document, and then periodically post them to my tumblr (RIP). Lots of Marty McConnell, Dorianne Laux, and Dorothea Grossman. As for a particular poem that I loved when I was a teenager, "Scheherazade" by Richard Siken comes to mind!
I'm a Libra, don't make me choose! Kidding - there are so many I love, but right now I'll choose this excerpt from Citizen by Claudia Rankine. I love her everyday, yet striking and memorable imagery; how she uses restraint to run free.
