Loose keys on aluminum MacBook

Is it normal that the enter key on the keyboard loose? I just moved my finger to it and it moves without pressing the button down. Also, when I can see the bottom of the enter key better then the other keys on my keyboard. This also includes the shift key as well. (It is loose too.) But the enter key seems to be even more looser then my shift key.

 

When you touch the enter key without pressing it down does it move? And all the keys on my keyboard are kinda like that but the enter key is the most loose one. It is a pain to take it to the Apple Store since it is like an hour drive. Speaking of Apple Store, do I have to make an appointment in order to talk to a genius?

 

Wow. I just turned more lights in my room and I found out the enter key is slanted. It is not in the middle it is more on the right.
