Unreliable Narrator: The Neighbor Girl

Lately we've had this issue with a young (no more than 5, likely younger) neighbor girl just walking across the street and into our house like she owns the place.  It's odd but mostly fine until a few weeks ago she came over on a Saturday morning while we weren't home and she ended up letting the dog out (who thankfully didn't run away).  We were very confused as to how the dog got out when we got home and were puzzling over it all day when our little visitor made another appearance at 9pm after she was supposed to be in bed (she snuck out of her house and came over to ours because she "wanted to play").

While we were asking her questions to figure out what was going on before taking her back home she told us "I like your dog but he was scary when I opened the door and she jumped at me" which told us how the dog got into the front yard.  Then she continued the story with "And then my dad saw him [the dog] in the kitchen and he got scared too and we had to get him out of the house and I didn't know what to do" which was likely untrue...  Then she noticed the shark shaped blow up pool we have in the living room (the baby plays in it) and she asked what it is. I told her it's a baby pool, and she said "But it's a shark!" as though these two things cannot go together. She then proceeded to tell us a story about how she went swimming one time and saw a shark and the shark came up and bit her one the toe "right here" and it was very scary and hurt a lot.

Little kids are the best unreliable narrators in the whole entire world. I could listen to them spin tall tales forever.
