This is a good question.........
I have met some genuinely lovely people on this forum, that if we lived closer perhaps would become close friends even........but as we speak I probably have 3 good friends in all the world. they live in the far-flung corners of the world, and we only converse via phone and email, but if I called because I was in trouble, ill, or in difficulty, etc, ANY of them would jump on a plane and come to me. This to me defines a REAL friend.
I have been "in the firing line" several times, and had some decent blokes with me, I would cover their back, and they mine, and formed a close cameraderie with them, but when we all left, have never heard or seen them again. So what IS a real friend?
Very hard to define, but in my opinion, it must be somebody who cares, will listen to you anytime, will help you anytime, and would be sad and upset if anything happened to you.
Either way, if that IS the definition, then I have three good friends and some brilliant acquiaintences, some of which I have met on this forum and would do anything I can for if they ask me.
This of course does not include my partner Zena, whom I love and adore, and consider my soulmate and confidante.
