Not just commenting on their attractiveness, noticing small things about them that other people may not notice, comment about their personality something you find positive/intriguing about them. And just be confident in yourself. Also be inquisitive. If she don’t want that she ain’t it
Anything interesting, compassion, intelligence, curiosity. But that’s my personal preference. Everyone’s different, and you’re also trying to attract the right person for you. I might not be the kind of person you’d like. If you put your authentic self on display, you’ll attract people who like your authentic self. It will save you time later.
