Lost keys=lost mind?

I think I have lost my keys. On Friday, I took Rei and Ian to the video store and we rented some movies. Then we got pizza. Getting home, I was juggling pizza, movies, Ian and Rei, just trying to get them into the house without dropping the pizza. I think I lost my keys somewhere at this time. I've turned my house upside down and I can't find them. I have a terrible feeling I may have thrown them away. I've tried to remain positive about this, but really, it sucks. This is the second set of keys I've lost in 5 months. I do think I've lost my mind. >.<
