Person
Remember how the radical version of this kanji meant person because it's a person walking from the side with their arms down? Well this is a person too!
Know the radicals, and you shall know the kanji.
にん, じん
ひと, と
None
Only one person at Nintendo (にん) complained about the new jeans (じん) policy, and that person was you.
Imagine how angry you were about the policy. You'll have to come up with something to be angry about yourself (pick something that would actually make you angry, like maybe you're only allowed to wear cut off short-shorts jeans at Nintendo now), but if you pick something good, you'll definitely remember the two readings for this. Just remember you're working at Nintendo, and the policy has to be something about jeans. Then, imagine yourself as the only person complaining and everyone else in their dumb jeans (or lack-thereof) shaking their head at you because you're being a fool.
