Some friends recently had a spate of holidays. Poor pets, sure, but things weren't all peachy amid their travel both around Australia and overseas. They didn't get mugged, lose luggage, hijacked or get Bali belly... but they did forget their vibrator, the one nicknamed 'Kevin'. It mightn't sound like that big a deal, an undeniably first world problem, but it did interfere with their holiday. Whether 'Kevin' was an expectation for partner play or solo time is largely irrelevant. The fact is that he wasn't where he was needed or wanted. The bastard.
Whether you are fly-in-fly-out (FIFO) or a more traditional seasoned work traveller, once you get back to your hotel or donga after a day working, you appreciate that there's a lot of time or opportunity until you wake to do it all again. Those 'what to bring' or packing lists for travellers never mention that it's always a good idea to bring something for your solo time and it pays to be prepared for those long lonely, isolated hours.
