<p>People are always talking about "S" and "D". Who are these mysterious people with one-lettered names, and how does everyone know who they are? Do they work for MI6?</p>
<p>son / daughter?</p>
<p>LOL......... yes, and DS and DD are <em>echem</em>retarded initials for darling son and darling daughter....well i donno, i don't think it takes much long to just write out the whole word "son," since you end up using caps lock or shift anyway.</p>
<p>Yeah, it's son and daughter. I was confused about that too. I don't think it's that much of a hassle to write "son" and "daughter," but whatever.</p>
