Another Key

I think I may have solved my key mystery from Angelo. Remember when my truck key mysterioulsy went missing a few posts back. I think I need to get a new key ring!! I went to the store last night and had 2 keys on my key ring- my truck key and a house key. I just had my wallet and my keys, went in, grabbed a few things, and came back out to my car. When I got back to the house- no house key. So, my theory is this- my keys simply fall off my key ring. In this situation the lady I'm living with was luckily home and had another key for me to use :)
I plan on getting a new key ring today!!
