Dead Pixels

I just found a dead pixel on my laptop screen and it’s becoming larger and larger in my mind than it actually is. I’ve been retracing my steps yesterday but no matter how hard I try to recall, I can’t remember anything I did that could have caused this speck to appear. I wish it was just in a corner, but somehow it decided to appear on the lower mid-third of the screen. NOTHING I can do about it but how I wish it would just go away.

And I was wondering how 1 mistake could ruin someone’s reputation; or why people always remember what you did wrong and not the many things you did right... well, it’s one or two pixels among thousands of pixels and it’s driving me crazy.
