I don't mean to be bitchy, but I've got some tips for you about speech etc.
The phone call should've been something like this:
"Whaddup?" I asked.
"Wanna go to a concert with me?" my friend replied.
And so on.
For the talk with Tyson, it needs capital letters, and the same format as the phone call;
"Tyson?" I asked.
"Miss me?" he replied.
Hope this helps a bit. :)
