Want to write something flirty to a girl I already know

I know this girl about 6 years from high school, once we graduated we hadn't see, talk and hear each other about a year.
Today I added her to my Facebook friends and she sent me a message, I'd like to write her back, but something flirty, I'm sick of the dry questions/answers such as:

Quote:

---

She: how are you doing?
Me: I'm great, and you?

---

and so on...

Somebody having any idea what should I write her?, she sent me

Quote:

---

"Wooow,
Hello hellllo,
How are you?
It's been long time no heard from you hhh"

---

(yes she added hhh)

Don't know what hhh means, but if you want flirty, try, "I'm over the moon now" as a reply.

She'll ask "why"

And you'll come up with something along the lines of..."I've got buttocks, so I'm always over at least half a moon, even when I sleep the fetal position. Plus I never thought I'd get a chance to talk to you again. That's two moons! That's once in a billion smurfy blue moons."

A bit odd, but it might just work.

May be I should write her something like that
"Hello hello you too,
Maybe you got another question?, 'cease you might not noticed that but life is the bubbles.
Ditto you, where have you gone?, not heard from you, not saw you, what's going on?"

It's more in the moment. Difficult to pre-write for a conversation.

Just say hi back and ask her what she's been up.

We could load you up full of lines, but they probably won't lend themselves to your conversation anyway.

Start chatting and let nature do the rest.
