To say that someone is vain because they ask for a picture is ridiculous to some extent and unfair. Attraction is not on looks alone. Beauty is in the eyes of the beholder. I personally have gone out with “gorgeous, absolutely beautiful and really good looking” to some yes , but not me. That’s reason I ask for a picture, but not always do I ask for one. I have been fooled too many times unfortunately.
Ah gut K’vittel too all of Klal Yisroel!
