This is rude and annoying. When replying to a message you should be using your mail client's reply function, rather than start a new message and paste in your quotations. This should preserve the subject line and add the proper In-Reply-To: header so that the message is properly sorted into the existing thread. If you have been using your mail client's reply function instead of composing a new message, then your mail client is broken so please use another one.
