When on your first date in the movies with your new girlfriend, you wallrun climb up, and pop over straight to the seat because you didn't wanna walk all the way around the wall and up the stairs coming back from the front desk.
She freaked.
Also, when you forget a wall run with sharp rocks tore your finger up the day before, and you out of pure instinct do a wall run climb up by accident and forget entirely that you have missing skin until you feel the wall on your fingers insides. =3
