Day Dreamer or Liar

Yesterday when Jeanine and her family came over for dinner, Mitch was wearing sunglasses. My mom noticed them and asked Mitch about them. The conversation went a little like this:

My Mom: Mitch, it's dark outside. Why are you wearing sunglasses?

Mitch: 'Cause we went to the beach today.

My Mom: You went to the beach today? (said with surprise and raised eyebrows).

Mitch: Yeah. And a crab bit my toe!!

He then pointed at his toe, became distracted by toys, and ran into the toy room. My mom and I looked at each other and laughed. Later on at dinner, I thought I'd bring the topic up again. This time, the conversation went a little like this:

Me: Mitch, did you go anywhere fun today? Like the Beach?

Mitch: Yeah, I went to the beach and a crab bit my toe.

Me: A crab bit your toe? Were you swimming in the water?

Mitch: No, I was just looking for sea shells and I found one this big. (stretches his hands as wide as they go).

So you decide, Day Dreamer or Liar?
