Hahahahaha! XD I was walking my way through a sword-fighting scene, and had just done a super-cool spin-slash thing - and when I turn around, there's this little old lady standing there looking like o.O. I just sort of pretended nothing had happened, and she spent the rest of the wait for the bus standing as far away from me as possible. XD
The funny thing is it never would have happened if I hadn't had my headphones on - I didn't hear her approaching!
