"I don't want to measure your poop right now."

"Mooooommy, come here please." I walk upstairs and open up the bathroom door. "What's up?" "I just made a humongous poop!" my son exclaimed excitedly. "Good job, buddy." (what else am I gonna say?) "It's so big, you should look at it!" he continues, while holding up his hands to indicate an approximate length. "Oh, no thanks," I politely decline. "Okay, bye." "Wait, how big do you think it is? Can you go get a ruler?" Pause... (um, really? you want me to go find a ruler, stick it in the toilet, then somehow figure out the length of the poop you just made? and then what??) was what went through my mind. However, what came out of my mouth was that matter of fact statement that seemed to bring the whole strange discourse to an end.
