"Me: Like your hair. Not many can pull off red.

Her: Lol thanks ;)

Me: Give me your number if you're more interesting than just a hair color.

Her: I don't give out my number on the first conversation lol

Me: Hi, I'm [my name]. This is a new conversation. Give me your number.

Her: Lol Nice try hun"

Don't give a shit about this girl specifically, but if this happens again, what is the best way to proceed?
