Re: How to respond to "hello :)"
TominVegas is great. I'd say "Heyy how are you ?" She's obviously in a good mood, so that's good but get her to say that and solidify. I throw in the extra "y" on purpose. It's a little more fun and playful, which you can do since she clearly likes you. That's a lot of investment on her part. Don't get clever with lots of teases. She already likes you. Just get the conversation going then get a meet up established.
