Do you inadvertantly send rude emails/messages?

Not being able to see a person's facial expressions or the tone in their voice makes it easy to misinterpret their messages pretty easily. I see a lot of this or here and many times it turns into fights and hurt feelings. If we are only communicating by the written/typed word we need to take care of the way we say things if we want our communications to be received as we intend. People are going to argue on occasion, but there is no sense in arguing over miscommunication. As always, JMHO :)
