We only ever argue about politics and religion.
We had a fight last week which ruined a nice dinner out. We argued about what "belief in God" meant.
Lots of reasoned points which became more heated with statements like:
"I can't believe you would misconstrue what I just said"
"I'm only quoting word for word what came out of your mouth"
"That's so simplistic as to be laughable"
"Stop setting up straw men"
"Well of course if you take everything to its logical extreme you will always make me sound like an idiot"
Then "I don't want to talk about this any more." "yes i agree, change the subject"
Cue stilted distant conversation about nothing in particular ignoring elephant in the room.
Then semi-apology from each of us:
"Look I'm sorry I upset you but..."
"Well I'm sorry too but if you hadn't exaggerated what I had said..."
Then annoyed silence for a while. Annoyance melts slowly over next half hour or so as we potter around the house. Then one of us goes to the other for a kiss and a hug and says "I'm sorry I got so upset and Hirt your feelings", the other then also has to say "no don't be ridiculous, I was being a pedantic arse", "it was my fault" "no it was MY fault"
The apologies at the end MUST be genuine and both parties must really feel bad - either that they were in the wrong, or that they were in the right but handled it so badly that an argument ensued. Otherwise the whole cycle starts again!
