you can always find out more about someone

So i was talking to this one girl.. she's a pretty cool friend or w.e and we were talking about how u can nvr stop learning something new about someone. and i was like yeah that's soo true.. cause just the other night i was talking to my best friend. and he was telling me shit that i nvr knew about him or what i would even think he was into.. meaning like things he likes to do. so it's nvr to late to learn about any1.
