I think I know someone who has the same problem. There might be some sort of suppression why she can't speak her mind. I used to think she must simply be having an issue with her communication skills, but I notice as time goes by that she has some thoughts she wants to talk about but don't want to with me. She once said she'll tell me about this concern of hers one day but now isn't the right time. It's a bit disturbing and hey, this thread is under "depression".
Edit: I'll take your advice about writing. She does write well.

Thanks, guys.
