Poor communication makes for failure in relationships.

Communication is super important, or you could never get anything done. People aren't mind-readers. You can't go dropping hints or be passive-aggressive and expect anyone to understand what you mean or what you want.
There are a a lot of people who just can't read between the lines.

Besides, being passive-aggressive and non-communicative is just extremely immature. You might not be intentionally "playing games", but the other person probably won't see that.
You might be trying to be rude or mean, but what sounds ruder: just saying what you mean, or constantly dropping hints?

If a person who is blind and death can learn to communicate, so can you. Communication isn't just important in relationships, it's also imperative for just working with people.
