Sam was extremely busy during the days leading to Valentine's Day.
At night, he would be busy making the musical box.
If he was to purchase an 18 note musical mechanism with a winding key, it would be $15. That wouldn't do. So for a couple of hours during classtime, Sam would be researching on how to build his own musical mechanism.
However, he decided to upgrade it so that it wouldn't need winding up. He had many parts when making a robot so he devised a way so that the musical mechanism would wind itself up when it was in 'sleep' mode i.e. when the box was closed.
Of course, he would still add the musical key should the mechanism fail or if Betty wanted to listen to it again quickly.
Next, he had to decide on the music that would be played. There were so many to choose from. At first, he thought a lullaby would be good, but discarded it. Then, 'Twinkle twinkle litte star' came to mind but he threw that thought away.
