I do this a lot...when I get back from classes, I say to my stuffed animals, "Hi, guys, I'm home!" And if one of them should fall from my bed or a shelf onto the floor, or if one of my die cast Cars happens to fall, I always pick them up right away, sit them back on the shelf, and say, "Sorry."
And zeldapsychology, I think it's awful that your mom screams/threatens those things at you.
