I thought her friend was female. Is that sexist of me?

he used their, which means he didn't assume the friend's gender. that's polite of him.

that's a nice way to break the ice.

they'll have a common friend I bet.

I know where this is going.

guess they'll drink beer all day everyday.

friend at a pub. that's a great thing.

how did she know which pub he was talking about? lol

ooh, now things are getting steamy. 

so you can take your dog to the vet anytime you want. that's a good thing.
