Siff didn't so much chose a life in the skies as being thrust headfirst into it and now attempts to live up to every stereotype there is about Air Sailors from the pretended pirate lingo down to the red bandana that covers her blonde hair.
Some people doesn't take the hint and insist she is either a barmaid or a dancer.
That's usually the same people who wakes up in an alley with an empty purse and a hangover of all times. Not that Siff knows anything about it.
As far as she is concerned that is what guys do when they are on landleave
(The fact that Siff got out of the night with a heavier purse is a completely unrelated matter and noone can prove anything anyway).
