I guess I made a mess out of it ... was confused at first but I thought I played it well, so I am even more surprised. We exchanged some funny role playing messages, building comfort and all. Then all of a sudden, she strikes with:
HB: bla bla ... will you go to the coming elections?
ME: I usually dont.
HB: -15 points for you then :/ I`m dissapointed
ME: Seriously? You wanna talk about politics?

HB: I guess that is hard to do with you

(the smiley face, I thought I was safe)
ME: This is where you are wrong

(made a mess right there)
HB: Oh well ... good night
ME: Good night
"This is where you are wrong" line was stupid I know ... should have transitioned right away to something else ... or maybe even try with "I am to tired right now, but tommorow I challenge you to a debate."
What would be the right move? And how do I repair this mess now?
