Scenario-

You, are a fellow mermaid/merman/non binary merpal, living in a lake with everyone else. One day, you were minding your own business, when you heard a loud splash, along with a yelp. The yelp was almost like a child, which confused you. You then swam over to the sound, seeing a little girl around the age of ten/thirteen, who had a grey tail with a matching bra. She looked a bit scared, and shocked as she looked at herself again and again.

You?
