How to remember things about people?

How do you guys remember things about people?

The RA supervisors at my college told us that we should try to remember something about each resident to connect with them, but I really struggle to remember things about people. Well, more like, I struggle to CONSISTENTLY remember things about people. I might remember that thing you said one time or that you hate Yorkies because one bit you, but I might not remember your birthday, our anniversary, or even your name lmao. I brainfart my friends’ names 24/7.

Anywho, I thought about writing things down about every resident but that feels creepy? Idkkk, I have a whole notes for gift ideas for people I care about that I write in whenever they talk about their favorite things or something they’ve been wanting, so I was thinking of doing that, but it feels a little weird to have a file on every resident 😭😭😭
