I had a fear of flying. You could have never gotten me to even agree to go on a trip if a plane was involved, but my sister that lives across the country needed a sitter for a week and my mom was going, who also has a fear of flying, heights, and confined spaces. I thought it would be good for us to get over our fear together. It really wasn't bad at all. I actually enjoyed it. We both would do it again without even thinking about it.
