Does this dialogue bother anyone else?

Sometimes, there are things that come up that really bother me to teach.  There's nothing I can do about it, though.  For example, I have to play this dialogue for my students this week.  It's a listening thing, so I'm hoping that they'll miss the finer points and not realize how bad it is.  Ugh.  I grit my teeth every time.

What do you think?

Uncle John: Is that you, Yujin?
Yujin: Yes, it's me.  Nice to see you again, Uncle John.
UJ: Me, too.  How was the train ride?
Y: It was OK.  It only took two hours.
UJ: That bag is heavy, isn't it?
Y: Well, just a little.
UJ: Let me help it.
Y: OK.  Thanks.
UJ: Don't mention it.

Am I a freak for letting that get to me?
