Don't tell someone your number on Instagram

I have decided I am going to copy down a text conversation that I've had with someone, no matter how weird it is.
I'm not going to tell you who the conversation is with. Haha. They will be known as "friend". Here goes! (P.S. at first, my friend doesn't know who I am at first, because I found her number on Instagram) (P.P.S. when I do parentheses, it's not really in the text)

Me: Hihi:)
Friend: Who's this
Me: Lol
Friend: Who is this
Me: (Right here, I text the person's name)
Me: Yes :)
Friend: Who is this
Me: One of your friends
Friend: Tell me who this is
Me: That would b funny if u knew who I was
Friend: I am not texting u until u tell me
Me: Brat :) you deserve a kick (We do weird stuff to each other like that, but friendly)
Me: Guess who?
Friend: Who
(I send her a picture of half my face)
Me: Now can u tell
Friend: Oh hi ____ (She says someone else's name that isn't mine)
Me: ???
(I send her a picture of my whole face)
Friend: Anika!
Me: Yes :') I found ur number on  ur Instagram
Friend: Haha
Me: Whatevs
Friend: Oh wow u are so funny

That is the second time I have found someone's cell phone number on Instagram. That is my today's lesson- DON'T PUT YOUR NUMBER ON SOCIAL MEDIA UNLESS YOU WANT THE WORLD TO KNOW WHO YOU ARE. Well, at least you can't say I didn't warn you.
