"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.Also, is this whole thing (having a sexual affair) a good idea?"She asked me to stay and she told me to sit anywhere" Again, it's what you do when you invite a guy to your place, i.e., anywhere you want is fine; no big deal).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.He sits on the floor, they "rap" all night until she has to get some sleep (no sex, missed his opportunity), he sleeps in the tub (could have been on the floor, but tub is funnier), finds her gone in the morning, lights a fire and thinks about it.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.
John said about his songs "They're only words, they don't mean anything". It is about a guy having a sexual encounter in front of a fire place. By the way, Jan and Dean did a great version of this song!
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!
She realizes it's getting late, she really is very interested, and is trying to get him to kiss her/have sex with her. "She told me she worked in the morning, and started to laugh." Exactly that! maybe I meant she turned me down and I torched the place! One day I will ask him, and then I will know if I was right or not! The song has got to be about an affair if Lennon said it himself in Rolling Stone.
When you are a girl that has a job, as most girls do, after the sex is completed, you realize it is now 4 a.m., and you have to get up in 2 hours to get ready for work, so you are saying "I have to get some sleep! What happens during the encounter is what needs to be interpreted.
