Teacher Enrica - Turtle?

One morning mummy and Enrica were lying on the bed.

Mummy: Hey noi. I knew teacher Deborah brought an animal to your school the other day.
(I saw it from the childcare's newsletter.)

Enrica: (nodding her head...)

Mummy: Pretty big turtle crawling on the floor...

Enrica: No. It is not a turtle. It is a terrapin.

Mummy: Ah?! (I was startled.) Mummy don't know what is that. What is that noi?

Enrica: Terrapin is another kind of turtle.

Mummy: Em...( Paiseh...)
(Tracy used to have a few when she was in secondary school. Stinky little one. I helped her change the water most of the time. Damn it. There were ...terrapins.)
