On a recent WhatsApp call, Middle Sis asked a question that stumped us. It was completely irrelevant to the conversation, but we humoured her and immediately stopped everything to deal with it. Middle Sis' question? "What and where is the Cloud ?" Well that was all we needed. It resulted in a monumental round of speculation, ultimately leading to a further list of "Questions that have always bugged us." I mean we haven't lost any sleep over them, but we would certainly feel a sense of relief, perhaps even euphoria if they were answered.
