['My friend was supposed to meet me at my apartment so we could eat at Starbucks.  But she ended up wanting a full body back rub.  It was a nice change of plans.']
Oh, that's...interesting. That does sound like a nice change of plans, not only because Starbucks not seem that fun anyway. Hopefully she returned the favor?
I just had a friend come over today.  The plan was to hit Starbucks...but plans changed and she asked for a back rub. It was a nice abrupt turn of events.
