Mr Roboto?

Short Term Lodger Dude just left. He's headed off to his new home, happily, hopefully.

After putting him up for 5 days, treating him to lunch at a halfway decent sit down chain restaurant, offering hours of (solicited) advice about how to present at our colloquium, and other various aiding and abetting over the week, he finally thanked me, halfheartedly...

for opening the door as he left.

Now, I know I'm not the best host. I didn't cook dinner for him. I didn't wake him with the gentle smell of fresh roasted coffee or sprinkle the fold out couch with rose petals.

It's not like I think I need to be praised to the sky, I just put him up for a few days, but "thanks?" Is it too much to ask for a "thanks?"

Am I being a prick for being annoyed about this?
