We're talking about relationships, wondering what people's home lives are like and saying how we both thought we'd never find someone we could live with - soppy bollocks like that.
"But you can get too comfortable with someone," says Betty.
"How?" I say.
"There was this woman I used to work with. One day she said how comfortable her and her husband were in each other's company. So comfortable that when she took a bath, he often came into the bathroom, sat on the toilet and had a shit."
"Christ, that's disgusting," I say. "Did he purposely wait till she was in the bath?"
"I don't think so. He used to put a towel over his head while he did it. So he could concentrate on what he was doing."
"How could she say that in the office?"
"The strange thing was, the other women in the office didn't bat an eyelid. They were completely indifferent."
"Maybe that's the norm. Maybe we're not as close as we thought."
