"And when I awoke, I was alone: this bird had flown." He wakes up and finds that she has left for work, so he gets up and lights a fire in the fireplace and has a cup of tea, contemplating what has happened the night before (the affair/affairs). (She invites him to her bedroom for crying out loud -they know what's going on - their drinking) She asks him to sit, but there is no chairs - she wants him to sit on the bed.He sits on the rug waiting for her to tell him to use the bed.The bird having flown is an allusion to the marijuana smoke having floated away, so he lights another joint.Also the line "she once had me" means "she had him at hello", as one might say, and also that she cheated or deceived him (to be had) -- he thought he was going to have sex with her.He slept in the bathtub because there wasn't a chair and he was too stoned to leave.I agree, this is about as straight-forward a little tale as could be.Join her in her flat, "sit anywhere" would be an invitation to the bed since there's no other furniture as her laughing points out, but he's too shy, too married, or something.
She was a little embarrassed, flattered and teasing at the same time.
This song is about a memory from a cabin in Norway made of Norwegian wood and the girl of course.
If you guys have seen twin peaks and been to the state of Washington , there you have the Norwegian style of cabins.
John had said, and I believe it's true, that he was speaking about all of the affairs he had that his wife didn't know about.
I think he felt guilty and wanted to confess, but knew he could not, so he did the next best thing, wrote a song about it!
As it is, the phrase indicates that the words "the fire" refer to a specific fire that the listener would already know about in this house or apartment, such as what would be in a fireplace.
