Surprise, surprise

I'm full of surprises! 


My dear boyfriend still hasn't got any idea, why (and for what) I needed his passport number today. 
Am I going to send him back to France via post? 
Am I going to sell his kidney to get some money for our apartment? Hih, I guess he figures it out sooner or later... Or then he just doesn't. 
What do you think, what have I done (those of you who knows, this is the moment to be quiet)?
