I was reading the thread about text openers earlier and decided to try one out, take a look at this convo and see if you can get anything from it. It seemed to work a charm for me.
Me: *blank text*
Her: ?
Me: ? Why send me a question mark?
Her: You sent a blank text
Me: You don't need to make up excuses to talk to me [her name]. I don't bite
Her: haha you did tho
Me: Lies! Anyway, I've got a surprise for you next time you see me...
Her: Noo

awrr what's that?
Me: Well I can't tell you, it wouldn't be a surprise then would it?
Her: haha teeeeeeelll me!
Me: I'll tell you in my next text...
*long pause*
Her: Tell me now!
*long pause*
Me: I bet you looked at this text expecting me to tell you didn't you. Sorry, I'm not
that easy
Her: Oi please tell me
Me: awww looks like I'm to busy to keep texting. You'll just have to keep
wondering what it is. Text me if you come up with any ideas

Bye x
Her: Ohh foof you

It had a playful start by making it out that she's really the one that wants to talk to me. The whole surprise thing now keeps her thinking about me because she's wondering what the surprise is. Not sure where I'm going to go with that yet, maybe I'll just wing it lol. Looking back on it, I possibly should have said something like "What's in it for me if I tell you?". It has also now shown that she's game to meet me again. Hope it's helped you, feel free to throw a few pointers my way as well.
