I have a friend of mine that refuses to date within her circles because the men that would ask her out, from that group, had already dated other women of the same circle...so one could understand how could make her feel uncomfortable?
Three seconds. That's how long it took. Your shoes. Your posture. The way you held your drink. Whether you looked at the floor or looked at her.
She already filed you away. Interesting. Boring. Safe. Bold. Before you even opened your mouth.
Everything you say after that is just her confirming what she already decided.
So stop rehearsing lines. Fix the first three seconds. Stand tall. Look up. Smile like you mean it. Walk like you belong wherever you're standing.
The words come later. The impression comes first.
