Up till now I always thought bickering was just something children did and they outgrew it. Of course, there's sometimes a reason to have a 'real' quarrel, but the verbal exchanges that take place here are just plain bickering. I should be used to the fact that these squabbles are daily occurrences, but I'm not and never will be as long as I'm the subject of nearly every discussion. (They refer to these as 'discussions instead of 'quarrels', but Germans don't know the difference!)
