Is "chemistry" with another person something you can detect just by seeing them?
I know someone who has been divorced for 17 years. She hasn't dated, won't even go out for a drink or dinner with someone. When I asked her why she refuses to even go out to dinner with a man (several have asked her for dates), as she complains about being lonely, her answer was "I haven't felt that chemistry with anyone that's asked me. I have to feel the chemistry is there before I'll go on a date."
I don't understand how you know whether there is chemistry or not without getting to know the other person on some level. She says there should be a spark, just from seeing them. I think she's looking for love-at-first-sight. What are your thoughts?
