So a purple haired girl with a Pokemon name appeared in my okcupid matches yesterday. Was cute too.
But she smokes. :|
Go for it. Sure, it's gross, but you'll learn to deal with it.
Plus, you could always carry around a pack of gum and offer it to her randomly (you would have to take a piece too or she might think you were trying to drug her).
If she's smart, she'll pick up on it and (if she likes you) either start doing it herself out of consideration for you, or consider quitting. If she's not smart, well, just keep doing it. >_>
