Walking Plant?

Yesterday, when I came home from work, one of my plants had moved from the corner of the table near the wall, to the middle of the table where it could get more sun.

I just stared at it for about a minute straight thinking:

"How did it do that?! It couldn't just do that.
Did I move it and forget? No, I wouldn't move it there.
Did someone break into our house just to move my plant! 'Alright, we've got all the good silver (Ha. Like we have good silver), oh wait. This plant's not getting any sun! Let's move it before we take off!' No...
...
OH! Kam took work off earlier today to study! Kam moved my plant so it would get more sun. Aww! Kam cares about our plant!"
