Hey guys,

I had a conversation the other day on facebook with a girl i liked and I couldn't figure out how to escalate it too well.

Don't really have the convo saved but it went something like this.
(we both wanted this certain job in retail and i went to apply for it that day)

Me: The job at amazon was taken by the way

Her: oh sorry mate
yea by me
haha just jokes, i wish

Me: yea its all your fault
if you did... (this was at her getting the job)

Her: what? why is it my fault?

Me: because you were supposed to get the job of the manager and hire me

Her: oh yea thats right
if i did? what you would punish me ?

Me: yea thats exactly what i'd do (i'm slightly evil by the way)

Her: I'm way too sweet and innocent for you to be mean to me haha

Me: Gee i must be talking to a different (her name) haha
that wouldn't stop me, it makes you more vulnerable

Her: (surprised you could do little devil faces on facebook haha)
how do you do an angel face?

Me: (tried a couple of attempts and failed till i got it right)

Her: oooooohh. cute

Me: It was pretty epic fail, i mean i was supposed to be all impressive and whip it
out straight away but yea couldn't quite pull through haha

Her: That sounded sooo wrong haha anyways i'm off. goodnight x

Me: I knew you wern't sweet and innocent, night night

As you can see I could have escalated a lot more when she started talking a bit sexual but couldn't quite keep the sexual tension.

What do you think? what do her replies and convo mean? Is she interested?
