Try to keep in mind that writing styles may cause some messages to come across as sounding abrupt or even antagonistic when that is not the intention of the sender. Take time to read and fully comprehend what has been written before you reply, especially if the message provokes a strong emotional response. If you don't understand a particular item, ask the sender for clarification before replying to an incorrect conclusion. Electronic mail cannot replace personal contact. There is a tendency to be less formal or careful which can sometimes provoke anger.
