Okay so I really am having a little friendship dilemma.

So on this social-media thing call instagram, I changed my username to something that had to do with dance.. I changed it to maddydancess.
My friend has a similar user name and she got all mad saying I copied her, but I really didn't.

She takes dance; and I don't and now she's like "oh you cant be a good dancer if you don't take lessons" and im like "well I self-teach myself."
(btw I am very good at dance and gymnastics although I don't take it.)

Now shes really mad at me and I did nothing.

Who do you think is right in this situation?
Should I change my username for her?
And do you have to take dance to be a dancer (I though u can be anything u wanna be) ?

love maddy and best answer gets 10 points
