I'm not afraid of heights when I know I'm attached to something, or there's something I can hang on to. I've never tried climbing (other than trees *lol*) so I don't know how I'd handle that. I don't like being on the edge of cliffs though, cause I always feel like I'm gonna slip, or topple over, or sometimes I even feel like I wanna jump... that's when I back away quickly and go sit down!
