I went into this with the best of intentions.

I remember watching an episode of Six Feet Under with Juliette once, in which one of the characters responds to his brother's morning greeting with a detailed description of his baby daughter's feces. Not in complaint, mind you, or for gross-out value. No, no, this guy was proud of his daughter's poop. This poop was an accomplishment. The best, most interesting poop ever. This is what new (-ish) parents do to their siblings over morning coffee, I guess. Talk about poop.

"Oh God," I said to Juliette with a roll of my eyes. "Is that going to be me some day?"

"If you don't want to be that way, then just don't be that way," she replied.

"I'm not going to be that guy. Please don't let me be that guy."

People, I am that guy.

This morning after breakfast, I was in the middle of composing an email when Jason walked back into the kitchen, his mother having just finished dressing him.

"Owie!" he yelled. I looked over, and he was bent over and holding his crotch.

"Does your penis hurt?" I asked.

"Yeah," he replied. This is not unexpected. He complains about his penis a lot. He also laughs about it a lot. Let's just admit it: the kid likes to talk about his penis. I would normally dismiss this with a kind word and a hug, but it dawns on me that the little step he's doing looks a lot like a pee-pee dance.

"Do you have to go pee pee?" I asked. "Do you want to sit on the potty?"

"Yeah!" he whined back, and ran for the bathroom.

We've been doing this for several weeks now. Jason claims to have to pee, we take him to the bathroom and let him sit on the potty, shortly after which—nothing having happened down below—he declares "All done!" and then wants to go play in the living room. I might have expected this time to play out the same way, but there was a certain, shall we say, urgency to his body language that made me think this might be the time.

It took some coaxing. He was ready to give up early again. I convinced him to sit a little longer, to let the pee out. That's what I actually said to him. "Let the pee pee out, Jason. Push." I honestly never thought I would say those words to anybody. I mean, I guess if you'd asked me, I might have shrugged and said "Yeah, I guess," but it just never crossed my mind. Some day I will be telling someone, in all earnestness, to let the pee pee out.

A little grunting and a look of concentration came and passed. "I did it!" Jason declared.

"Really?" I asked, not quite sure if I believed him. (Jason's idea of truth is a little flexible, you see.)

"Yeah!" he said.

"OK then," I said. "Now stand up, and we'll look and see what you... Whoa, that's not pee pee!" Staring me back at me from the little basin my son just stood up from is a little pile of poop.

And here's the thing: it didn't even occur to me to be grossed out. Quite the contrary; I cheered. "Yay Jason!" I shouted. "You pooped in the potty! What a big boy! I'm so proud of you! Yay!"

If you had asked me five years ago if I would ever be elated to witness someone defecating, I would have wrinkled my nose. Sure, I understood that you have to make a big deal out of successes when you're potty training a child, you have to act like you're excited about it. But surely that's all it would be: a show of positive emotion, masking the underlying truth that I had just had to watch another human take a dump.

Nope. I really was as excited as I sounded. So excited, in fact, that I had to tell you all about it.

Yep, I'm definitely that guy now.
