Like you I would respectfully listen to her but what convinces her doesn't necessarily have to convince me. The type of observation that would convince me is from someone who has credibility in their statements (which your friend seems to have) and also the ability to accurately interpret what they observed. That's why the ones who would convince me needed both character and outdoors experience.
I have a friend whom I have been convincing that the stories she tells would make great multimillion dollar tv series. So in the last few years she has been recording what happens to her.
The thing is, she conveniently forgets to record when the blue light comes down from Heaven and delivers her a message.
Weird, huh?
