I Know That You Know That I Know

People who knows me will know that I'm spaced out alot of the time and I have a memory equivalent to a goldfish. I may seem to know some things but I don't. At the very same time, I do know other things I don't either seem to know or seem to care. I choose to believe I understand and know what is going on although I'm often mistaken. I think I know what I should know... I think... I hope... All we can do is hope to know we know right? I don't know if I know. I'm lost. Or am I?
