The next morning

You awake with your limbs stiff and your mind foggy from last night. After a second or two, your memory of what happened came flooding back. Reaching over, however, for find nothing but empty bed. Confused, you look around. You notice an index card folded over into a little tent on your nightstand. On it there is a message:

“I had an amazing night last night. Sorry to run out on you, but I didn’t want to make a “walk of shame” after everyone gets up. I’ll see you soon! –Irena”

Well, what to make of that?
