How to say "I don't know you well"


I'm trying to tell someone the reason I don't want to do something is because
i barely know them. I'm not even sure if the verb I'm suppose to be using is
知る。I feel that might be really rude to say to someone. I searched around and
the only word I can find that might work is なじむ(馴染む)。 I also don't know if I
should use their name like Example : まだアリサさんになじまない = I'm not familiar with
Alyssa yet.




なじむ is rarely used for a person, so まだアリサさんになじまない is unnatural.

I think 知る、親しくなる、仲良くなる are better like ～さんをよく知らない、～さんと親しくなっていない、～さんと仲良くなっていない.
