Benjamin was deeply ensconced in a drawing project this morning, and was sharing a seat with Commuter Mommy. She was trying to work, so I tried to convince him to occupy one of the empty chairs, so as not to crowd his working mom’s lair.

Brandy was happy to share, though, and corrected my suggestion.

Benjamin shows off his little bum.

“He’s fine,” she said. “He can stay. He has a little bum.”

“And you have a…,” Benjamin started.

“Easy, Ben,” I warned, anticipating that he might be headed in the wrong direction. “Mom has a nice bum.”

He was unfazed. “Mom has a big bum,” he said, finishing what I feared had been his thought.

I held my breath. Brandy feigned shock and indignity. Benjamin giggled.

“And Dad has a large bum!” he added, with emphasis placed on the word large.

If this were a Batman comic, you’d have seen “Double zing!” in a bright yellow burst with a red border in the subsequent panel.

I’ll be putting in some extra miles on the bike this weekend.
