For me, it's not that I'm afraid of heights, it's more a fear of falling. I know that as a joke it's been said many times, but with me it's serious. Like if I'm near a balcony, I have thoughts of jumping off and it scares me. In a glass elevator, looking down and imagining if the ropes snapped. I know deep down that I wouldn't actually jump and that the chance of an elevator's pully system failing is minimal, so it's not much of a fear, but it still lurks. Not very strong, but it lurks.
