Can't Stand Heights!!!

When I was younger my dad who is also afraid of heights use to have me go up on the roof to clean the gutters from the leaves. There was no way I could stand on the edge and look down to the ground otherwise I felt like I would fall right over! I think it heleped a little being up there and always being safe so it's a little easier on me now, but If my dad wasn't more affraid than me I definatly wouldn't have helped.
