I am sitting at yours, waiting for you. You are going to return from work soon. I will wish you a happy birthday and play violin for you. I have even chosen the words to congratulate you.
Before, you were often discontent because I did not remember all these dates of birthdays and holidays, of this and that. This time, I did. It must be helpful, too, because you may be hurt with my long absence. You may also not like the fact that I came to your house without asking permission. But we are friends, does it really matter where do we meet? I promise that I will behave this time.
I run through the melody to remember it. Something is wrong. Right, of course, it is "We wish you a merry Christmas", not "Happy birthday to you". Two popular songs with uncomplicated words and the easiest melodies to memorize, everybody learns them at an early age, is it hard to mix them up?
I correct myself strictly. Yes, it does matter. The inner voice that says this phrase sounds just like yours.
I glance at the watch. I will not have to wait for long – five minutes, not more. I have considered your walking velocity, the average capacity of the roads, and the possible amount of traffic jams. My calculations must be right. And yes, they are, because I hear the door opening.
And I remember that I haven't considered one little thing. You do not know at all that I am alive.
