Hypothetical Embarrassing Moment

Once upon a time last September, there was a charming masters student who was sitting in the salon getting her hair cut when she received a text message from her boyfriend asking her to meet him on campus with a CD he needed for a class assignment.  She agreed to meet him at a planter in front of the Joseph F. Smith building, a place they had previously met up on more than one occasion.  When her haircut was complete, she jaunted home to get the CD and headed to campus.  As was her habit, she called her mother during her walk to campus.

A fifteen minute walk later, she arrived in the JFSB quad and spotted her boyfriend sitting on the edge of the planter waiting for her.  His back was to her as she approached.  She walked up and sat down right next to him (like...right next to him...like you do with your boyfriend, you know?)  Not wanting to interrupt her mother, she didn't say anything to him, but began scratching his back in a oh-hey-it's-just-me-your-girlfriend-how-are-you kind of way. After a minute and a half of absent-minded back scratching, she hung up with her mother and reached into her backpack to get the CD he needed.  And then she turned to hand it to him....

....and found herself face-to-face with a complete stranger wearing a very amused look on his face.

At which point she so poisedly blurted, 'I don't know you!'

To which he replied, 'Yup.'

She tried to explain, 'I thought you were someone else!'

To which he replied, 'Yup.'

She sat there for a moment, unsure of what to do.  Would it be rude to just get up and leave?  After about 30 seconds of deliberation, during which she attempted to summon what was left of her dignity, she said, 'It was very nice meeting you.  Have a nice day!' and very quickly walked away.

Only to be greeted by her actual boyfriend, walking across the quad to meet her.

The moral of this story is:  what kind of person lets a complete stranger sit down right next to him and rub his back for a MINUTE AND A HALF without saying anything?  Honestly...
