DAY 11 Megalodon attack

I could call this day two of vacation bed ...  but let's move on. 
Here is a conversation between my 5-year-old and 6-year-old girls while in the car yesterday.  Unfortunately, I do not have visuals to accompany this post.

6:  What's that?
5:. It's an  'X.'
6: No, it's not.  an 'X' does this, that is a 'K.'
5: Oh- I wanted to make an 'X'
6: What's that?
5: That's my friend Journey.
6: What happened to her?
5: She got attacked by a shark. (very matter of fact storytelling)
6: (excited by this news)  What kind of shark?!
5: A megalodon.
6: A megalodon!  Did she cry?
5: No.
6: NO!  What? What did she do?  (seems pretty concerned about this situation)
5: She just called her mom.
6:  Called her mom!?  No way!  She would have died!  She has to go to the hospital! 
5:  Nope, she just called her mom.
6:  That's not real. Anyway, megalodons aren't alive anymore. (somewhat perturbed by this story)
5:  (nothing to say) (totally indifferent to her sister's rollercoaster emotions)
6: What's wrong with Journey's eyes?
5: Shark bite.
6: What kind of shark? Was it the megalodon again?
5:  No, I don't know,  just a shark, a grey and white one.
6: Grey and white?  Maybe it was a GREAT WHITE SHARK! (very excited about this idea)
5: Maybe, yeah- it probably was a great white. (willing to concede)
6:  What's that?
5: It's a 'Y.'
6: I don't think so, 'Ys' so down like this.  That's an 'X.'
5: Oh, ok. I thought it was a 'Y.'

My question as I was driving was first, "Megalodon? really?" and second- what the heck kind of picture did my child draw?  I know it clearly included another child who had endured multiple shark attacks and a few misshapen letters of the alphabet, but what else was going on? Most girls just draw rainbows and flowers!

Imagination is wonderful. :)
