I lose a lot of things. Recently, I lost my wallet in A.C. but got it back in the mail from an unknown source. I have lost my keys before, some cash, multiple hooded sweatshirts, t-shirts, shorts. I lost one sandal at a friends house once... that always bothered me. I was only there for two hours. Anyway, I was just looking for my Ipod when I realized something. An item becomes lost when you start searching in impractical places for that item. For example, if I was looking for my belt in the refrigerator, that item is officially lost. Not forever, but in that time frame. I was just looking for my Ipod in drawers I haven't opened since 1982. It turns out, it was underneth the very computer I am typing on right now.
I guess my point is... sitting down, taking a deep breath, and cursing very loudly is the only way to find something that is lost.
