That sometimes your "little angels" will seem like they are out to get you. . . and they really might be . . . or maybe they had a fight with their brother in the car right before school and they can't recenter themselves without some help.
Some days you'll wish you did something super boring like typing 80 words per minute and didn't have to talk to anyone but other days you'll go on a nature walk with your kids and look at leaves. . . and someone will pick something that looks a whole lot like poison ivy (even after your lesson about avoiding it). You'll momentarily freak out and then realize it's Virginia Creeper (same leaf pattern, but a set of five leaves instead of three)
Some days you'll see the light bulb go off in someone's head and you'll fall in love with teaching all over again and then someone will sneeze on you and remind you that kids can still be gross and intelligent at the same time.
Some days you'll be way too excited that lemurs at the Duke Lemur Center can "count" and your students will be slightly weirded out that you care so much about lemurs and counting objects. . .
and then one of your kids will tell you something cool about a yo-yo
And this is teaching.
