"Not Soph"

So, a while back I had this funny (for me) text exchange.
Thought you might enjoy it:

Unknown: Hey
Unknown: are you ok?

Me: Who is this?

Unknown: Remember it's Nic

Me: From where?

Unknown: Isn't this soph

Me: Nope

Unknown: Who is this

Me: Not Soph

Unknown: Bet
Unknown: sorry
Unknown: Wrong number 

Me: Yep

No special meaning, just a funny exchange.
