I am new on the job. Is it stupid if I make a list of things...

...that my cowokers tell me about themselves, so that i remember small details about them? That way, if I'm on the elevator with them or end up at the lunch table with them, i have something more personal to say to them besides " how is the weather...

I have about 20 to 25 people I just met over the course of about 2 weeks so I'm like 😕
