I have clarity, I have found inner peace, all makes sense now.
Aside from the feeling this girl or guy might be a creep, would you be inclined to inquire anything from them, or simply point them down the road to the closest clinic?
Depends on the situation and who the person is...
A related anecdote...I visited a Starbucks for my morning over-priced caffeine fix dressed casually (shorts/polo) some random individual approached and started asking about the tattoos on my leg. Not a problem, we chatted about my tats, whether they held any particular meaning etc. I got my drink and headed for the car, to go on various shopping exploits. The dude came running out of the store, waving frantically at me. From his actions, I expected anything from "can I have your number?" to "I just noticed your car is on fire" and was leaning toward the latter from his frenzied approach. So I rolled down the window, and he started in with "may I ask you a personal question?...{sure} Do you think you are a good person?...{yes, pretty good} Good enough to get into Heaven?" He was rather taken aback at my response "I am probably going to go to Hel." After some back and forth revealing my Heathenry and my belief that Hel (more properly Helheim) isn't the same as the Christian place of torment, he got back on his original track and essentially related the whole 'I have clarity, inner peace, the answer, etc. etc.' spiel. My reaction was essentially 'that's nice, have a good day. I really need to leave now.'
So, a rather harmless interaction with a religious prosletyzer. I am sure that he went back to his congregation proclaiming that he had spread the good news to some benighted devil worshipper or something.
If a personal acquaintance had done this, I would have been more willing to listen to his story, his reasons for feeling he had achieved inner peace etc, than I was for a complete stranger, who didn't bother to give his name before launching into a conversation about the status of my soul from a misplaced sense of superiority.
