Tell us about your best friend.
I'm going to (gonna) tell you about my best friend, Dave.
(Now) We've been friends for a long time.
I've known him since we were in high school together.
He has short brown hair, and large brown eyes.
(Now) He used to be quite strong and athletic, but now that we're getting a little bit older,
he's started to get quite chubby.
What else, well, he's very laid back and he can be quite humorous.
He usually likes playing pranks on me.
These days we mainly just watch sports and drink beer together.
All in all, he's a pretty good friend.
