Glad you found someone who 'walks your walk', Phil. I enjoy walking with other people as long as they are not 'difficult' - which has been described so aptly above. Luckily for me, the person I started bushwalking with is the person I still enjoy walking with the most. We can walk for ages in 'companionable silence' and then stop in the same instant to remark on something that has caught our eye. It always makes us laugh at how in-sync we are.
I've never had anyone outright lie to me about their abilities or preparedness before. Grrr! Can definitely understand why after a few unpleasant experiences like that people would prefer to walk solo.
