Confused

How do I really know that I've lost something? If I'm looking for an object and I can't find it, then I would know that I've lost it. But if I've totally forgotten about the object, then I would never look for it, even if it were missing. This is kind of confusing for my brain! This might be because I'm feeling very tired due to a very long work week! For me, this work week will not end until tomorrow! Somehow, I will get through this fifty-two-and-a-half-hour work week! I really don't have a choice because I'm on my own supporting myself. It is no wonder that I'm feeling confused this morning! I'm working way too many hours!
