No one tells you about the hickies

So last week when we were out of town, I went into the bathroom, glanced in the mirror and stopped in my tracks. There was some weird spot on my arm.

I looked closer, and then closer, and then closer. And then....what the hell?!

A HICKEY. And I immediately knew where it came from. A few hours earlier, Jack had playfully started sucking on my arm when I was holding him and I let him because I thought it was harmless. But it apparently wasn't. And I got to walk around the party with a hickey on my arm. They didn't tell me about this in the breastfeeding class I took when I was pregnant.
