I am going to talk with my friend even though I shouldn't
Why shouldn't you talk with your friend?
I love my friend but she is a recluse. She stays in her room all day and play videogames.
Your friend needs your understanding because she does not have many friends. You need to behave in an understanding way and be available for your friend instead of criticizing her.
But I don't want to be friends with a hermit.
She could be suffering from some mental disorder like agoraphobia. Have you asked her why she stays at home all day?
