What do I do? My friend might be E.T?

I have a friend that is named Ewaq (Ee-wa-kuh). It's really weird. Sometimes her skin turns green. Only a part of it. I'm very confused. I've only asked her once, "Are you an alien?" And all she said was, "Dop. ...." ?? What does Dop mean? I'm pretty sure she's an alien. Her name is so different from any names I heard. I tried to go to her house once because she said it was her birthday on October 13. (Weird.) But her house was locked. She opened the door and told me to leave. I saw a green figure and got scared. Whenever she gets mad, the person she's mad at just stares at her for 4 or 6 seconds and runs in panic, her eyes are a weird yellow-orange color. And her pupil isn't visible. On April Fools she never goes to school.....I'm bewildered. What should I do? Report her that she's an alien? Or just ignore it? Tell me, and thanks.
