I've gotten that feeling of someone before too. I've also had too many nice ones to let that one bother me. I think that it's also hard to interpret a message in words as we may take it one way as it may not have been intended to be.
i.e. when you speak to someone in person or hear a voice, you know what tone is being used and the moods..but when we write to one another, it is not always easy to decipher the tone being used and therefore miscommunications and misinterpretations happen.
does any of this make sense?
