For 13 to be unlucky would require there to be some kind of cosmic intelligence that counts things that humans count and that also makes certain things happen on certain dates or in certain places according to whether the number 13 'is involved' or not (whatever 'is involved' might mean).
I love physical kinds of comedy and getting down and dirty and doing stunts. When I was growing up I was always getting into fights with guys and usually punching out boys my age because I was a lot bigger and tougher. So I'm naturally accustomed to putting myself into the headspace of a girl who can take care of herself.
