I'm too forgetful, hence I tend to lose things easily.

I try to prevent though by keeping my room extremely neat and organized, and it helps... usually. But somehow I always end up losing things and later on find them somewhere I didn't expect them at all. Sometimes things end up in somewhat obscure places, too. The worst was probably losing my cell phone (because it was expensive and I'm a poor student). Found it in the washing machine the next day... then I pinned a note at the washing machine, saying "Remember to check your clothes" (and I'm not kidding, I really did - never happened again).

My short-term memory pretty much sucks. One second I'm putting something somewhere, the next I've already forgot where it was (and not to mention what).

My long term memory is pretty darn good. But, if I ever set my keys or anything down without being fully aware of it, they may as well have dropped off the face of the earth. I'm always looking for things I was holding just a second ago.
