The Twins

My evening had progressed slowly in the bar and I was on my second drink already, still without a lady to hook up with.
It´s not that I didn´t try, I used all the textbook examples but as soon they had gotten a free drink out of me their interest in me vaned quickly.
Thus I was sitting alone at the bar counter sipping on my drink when a decided to sit down next to me.
I eyed her from my peripheral. Golden hair, about the same age as me. She had that cute girl next door look.
“Hello”
Was she speaking to me? It kinda startled me at first, but I turned towards her and said hi.
“Care to offer me a drink?”. She seemed to tease me somehow.
“Sure, why not. One more or less wont break my bak account. I´m Peter by the way.”
“Joanna”, she said when divulging her name.
I instructed the bartender to give her what she wanted.
“I´ve been looking at you”, she told me.
“Uh-huh. What did you find out?”. I kinda knew the answer already.
“That you are a kind soul that likes to buy women drinks, but so far it hasn´t worked out for you”. She was definately teasing me now.
“But tell you what”, she continued, “as soon as I´ve finished this drink we can go to my place”.
What did she just say? I just stared at her. She was smiling a smug smile.
