I have a few people in my life that I just can’t communicate with. We talk, that’s not the problem. In fact, sometimes it is. I’ll say something and get a reaction that in my mind is totally left field. It isn’t until later while I’m mulling over the situation, that I realize what they thought I meant, and it wasn’t what I was saying at all. Part of it is different cultures, we both come from very different backgrounds, and part of it is just not knowing each other that well.
Because my goal is to have my books be as real to life as possible, I include that a lot in my stories. People don’t always get each other, even when they think they do.
