When you think that you've properly done something, but a few, uh okay a lot of days later you recently found out that it actually isn't so, what would you do? 

The thing is, the brain up in my skull up here said that i have done it! But it can't exactly remember when and what was the exact situation. Uh, it might be that I was like, daydreaming; ( I do a lot of those these days)then  the brain up here transfers it into thinking it was a REALITY, or that kinda thing... Or another reason is I might develop a mental disorder. Bipolar or that kinda thing? Damn. Darn. T.T
