I find it best to try and ignore the navy. Most of the banter stems from a massive inferiority complex.
If they wanted to fly, they would have made the grade for the RAF, if they wanted to be fine leaders of men, they would have joined the Army.
Instead, they wallow in their own irrelevance, sneering at the other services and using the RM as a cloak of respectability.
Most booties I know quite rightly think of theselves as the fourth Armed Service, not a bolt on appendage of the war canoe fleet.
Apart from that, the RN are delightful.
