Woman: ... is a real suprise.
Have a seat.
Alex, may i introduce you. My friend Dirk.
Dirk, this is my friend Alex.

Alex: Dirk?

Dirk: Your friend?

Woman: Yes, i had sex with both of you. (i don't know, how can i describe in english?)
Don't look so strange!
I'm still the same person.
Dirk, you're so amazing in bed... but you don't know how to eat good; hot dog eating at IKEA?

Dirk: I think it was very beautiful.

Woman: Alex!
It's awesome, that you have money, but in bed? I can do it to myself.

Alex: One moment.

Woman: Honestly, every man for himself... thats not work.
But together you're perfect.
I have no desire to hide me.
Now we conduct an open triangular relationship.
And we raise our glasses.
Cheers.

And who gives me a child?
