Hi, (sorry for the long post but I hate it when wanting to help people if they don't even give a good background story!)
To make a longs story short:
Met this HB9, friend of my sister, which is pretty risky I thought.
Ran into her 2 times while at 2 different party's and we talked briefly but I went off every time, just not to give her too much attention. After the first time we met, next day she had add me on facebook.
We talked everyday on facebook, I told her to give me her number and got it.
Now, first message yesterday I sent her (after she gave me her number was):
background info: she had a photo on facebook of her and a friend on a toilet, and I was laughing with it because it's a little immature (we're both 20) and she was qualifying herself. and it was her birthday 2 days ago
ME: Tell me, who was the handsome guy you were just talking to on facebook? You should defenitely go grab a drink with him sometime!

xx
HB: Oh, yeah! a very anoying guy! I keep giving him signals to leave me alone but he doesn't get it! X
ME: Oh, yeah, I got a situation like that too! She's a friend of my sister and she can't shut up about her birthday! :p xx
HB: Oh, that would totally drive me crazy! There are some strange people on this planet, dude! X
ME: Yeah! Luckily we're both normay people! or anyway, for u that will still come... just don't take toiletpictures and we would be hand and glove! haha xx
HB: that picture belongs to my personality =d x
ME: Okay, then I will buy you a toilet refresher! against smelly pictures!

xx
HB: haha, thank you! I appreciate the gesture =d x
ME: I thought so! but i'm going to leave you now! (as you wished for!)

xx
HB: haha, i'm going to work for school! -_- x
So that was yesterday, went pretty good.. now, today I think I made a mistake
ME: Hey HB, I had a big problem today! I was shopping and saw the wall with toilet refreshers but I couldn't figure if you prefer lavender, pine tree or the barbie pink scent...

the last one is good, bought it for myself!

xx
(off course I didn't went to the shop, I was just joking, she knows that!
HB: hhmm, I'll go for the last one then! Doesn't sound bad! =d X
and this is the part where I probably fucked up
ME: Ok, will do! I expected that tough, it suits you!

there also was a special action with massage oil and with that you get free service from an experienced masseur but he has exams now for 2 weeks so that's a bummer for you! haha xx
she didn't respond to this message so I think I fucked up! I'm not going to send her another text or talk to her if she's on facebook, I hope she will eventually respond! I think I scared her off a little by bringing a massage up too soon
What do you guys think and what would you do? I could really use some help here! It's not like I'm a total noob and I'm pretty good with words but this wasn't a good move!
The worst she can send is: WTF? What are you saying now?
Then I will reply: Haha, so you ARE naive, that's so cute!
Would this be a good reply?
