hi, I kinda know what I'm doing, however, I'm not smart enough to make seem like I have an idea of what's happening...please help me form words. uh anyway you're supposed to write the key difference and obviously, it's basically the same thing but flipped ( but also I like to overthink thing and go " well it is flipped but the one looks wider so id. k that could be one too but it says difference, not differences so maybe not but you never know" ... good times )
