It turns out that I! use! a! lot! of! exclamation! points! in my writing. I've noticed it here and there but was sending a few emails today and it was very obvious. Seriously! Every! sentence! ended! with! an! exclamation! point! My elementary school grammar teacher would be ashamed.
So I went back and started revising. Ending sentences with plain old boring periods. But then, when I read my email, a period just didn't work. Who would write an email full of exclamations? Well - turns out it's ME! I went back through and changed back to exclamation points. I guess I'm just an exciting person. I just can't help myself!
