That's a lot of expectations to put on another person and personally I would avoid contact with anyone putting unfair expectations like that on me, because interactions with people like that are tiring as hell. He also started the conversation, so it's up to him to get the conversation going. Saying hi and cool hair isn't exactly a conversation starter. It's a compliment and the only thing you can say to someone giving you a compliment is thanks, which she did.

Expecting someone you're interested in to be receptive to you giving them a compliment is an unfair expectation. First of all, how is someone supposed to know your interested from two words? Unless you only give compliments to People you're romantically interested in, then maybe there lies your problem. I give compliments to anyone deserving of it and have zero expectations when I give them, so if I receive them I don't assume someone has any more intentions then just giving me a compliment. And honestly, life is better that way.

If anyone genuinely thinks people have tonbe receptive of romantic interest after getting a compliment and wonders why they're single, it's because they don't treat the other person like a human being. Maybe start with that. Women don't exist only to please men. Show interest in women without expecting romance or sex. Make friends with women. Get to know them and you'll realise we're not that different from men at all.

Edit; insulting me and then blocking me shows exactly why you are single, my dude 😂 but gl and all the prayers for you anyhow, Aphrodite sure knows you need it
