Dear Rentals sister,
Hope the navy's not being too tough on you. A few times a year in my little city of Perth (Australia not scotland) the American sailors arive in mass quantities for their R and R. Its cool because it provides a little bit of diversity throughout our city as their clothes, accents, and unusual behaviour make them stand out like a sore thumb.
The ones i talked to say they really dont like the conditions on the ship as its hot, sweaty with bad pay and generally unpleasant conditions but if you've been there since april there must be something that motivates you to stay.
Being away with such disciplined routine like that must really make you appreciate your time off and have you missing home, freedom, and family.....These are all assumptions though I really no very little about your situation.
Hope all goes well. And if you ever stop in perth for R&R let rental know to contact me, i'd be happy to play tour guide.
All the best.
