Blind Date

Greeting at the door:
Him- Trying to decide if she is as pretty as his roommate said she was.
Her- Hoping he's not as much of a creep as his roommate is.

Car ride to the restaurant:
Him- Keeps conversation familiar by talking about his roommate, discovering how much of the conversation she will dominate all night.
Her- Finds out how close he and his roommate are, creep factor is now generally known, generally unknowingly dominates conversation.

Dinner:
Him- Hopes she'll order something cheep-ish, finally determines prettiness factor, tries to eat enough to be filled, but not look like a pig.
Her- Hopes he's not cheep, decides if she does not want to go out with him again.

Car ride back:
Him- Decides whether he'd like another date, wonders if he's going to get dessert, chuckles at himself for thinking of 'dessert' right after dinner (depending on decision- hope he can get the mints out of his glove compartment without it being awkward.)
Her- Decides whether she wants dessert, chuckles at herself for thinking of 'dessert' right after dinner, wonders if he's just chuckling because she is (depending on decision- goes through her meal wondering if there were onions or garlic)

Doorstep:
Him- Makes a comment either stating that it was kind of nice, or that they should get together again sometime, according to previous decision either takes some action or not, accordion to her decision either gets some action or not.
Her- Either responds to possible comment made about a future date or avoids it, according to his previous decision she has the option to get some lip-service or not, according to her decision either grants him his wish or shuts him down like a bad date.

After date:
Him- Depending on prettiness factor determined either brags about getting action (even if he didn't) or complains to roommate about getting set up.
Her- Depending on creepiness factor giggles all night or makes crepes.
