Just who is this Mano??

Aie! Margaret screams, as she herds ants on our dining room floor. Mano! Mano! Come here, Mano! And then, a few days later, Josephine is talking on my cell phone (not the new one, which Auntie Pamela provided after the last was thrown to the floor in a pique of rage. Why don't people call me back?? Really? No really, it wasn't me.) Anyway, Miss Phinie-Weenie is on the phone chatting with... Mano?? Again, who is this Mano?? They just giggle and run away.

Lulu, do you know this Mano? She looks thoughtful. "No, no I don't."

"Margaret, who is Mano??" "Mano!" she yells cheerfully.

I think it might be their secret baby.
