MacBook Air Screen Not in Right Position

I'm not sure how to explain this but I have had a look at my MacBook Air 13" and I have noticed the screen is moved over to the right a little but and it does not line up with the body/keyboard surround. I feel like my Mac isn't perfect and it annoys the HECK! out of me. Also when I hold my Mac and open it it makes a clicking noise in the top left but it doesn't make it when I just open the screen and don't hold the Mac. PLEASE HELP!!
