Massage
See what I mean about missing nuance? Here is a prime example of how you can’t read tone through a text message, or watch someone try and keep a straight face as they attempt to wind you up. “I’m having a massage” is a pretty straightforward sentence, so Katy decided to try and be more imaginative when telling her boyfriend what was going on that evening.
I can’t imagine the train of thoughts that were running through his head as he read, and re-read the message, trying to work out what on earth was going on. Did he realize he was being pranked? At least she put him out of his misery in the end, poor guy.
