Sod's Law

Why is it that when you are really trying to do everything right, that the fates conspire against you and everything goes wrong? You spend ages writing a very eloquent e-mail, mentioning an attachment - and you forget to attach it. You wrote another, confidential, e-mail and inexplicably the name of someone else entirely gets added to the 'To' list ?? (Lotus Notes I hate you). You arrange to call someone at a specific time - and your mobile phone has no signal. You spend ages writing a very complex document - and it inexplicably gets corrupted - and no-one believes you??? Makes you wonder how Sod's Law coped before technology....
