A store for lefties exists!
I just learned that a store dedicated to lefties actually exists! I was far too shy as a kid to ever ask for help with stuff like this (and this is me generously assuming that there were accommodations for lefties available on demand to begin with). I simply... dealt with learning how to do everything right-handed -- a common experience, I'm sure. I can confidently call myself ambidextrous at this point in my life, but, y'know. I just may indulge in some left-handed notebooks and coffee mugs anyway!
