I am not entirely sure what I am supposed to say, so I'm going to say hello again.
There. That's done.
More enthusiasm, maybe?
This is awkward.
I feel the need to fill up the silence.
Should I tell you a story, perhaps?
No, I don't think you'll listen that long.
Maybe I could interest you in an anecdote?
But I am not sure what you'd enjoy.
A joke. A joke is a good idea, isn't it?
What if I offend you though?
What can I say knowing you want to hear me say it?
Should I try hello again?
