How to recognize when you're getting argumentative
Realize that there can be a blurry line between polite disagreement, and emotional argument.
People draw the line in different places.
The other person may be feeling more emotional, or less, about the topic or how the conversation is going.
Don't assume they're being insensitive, uncaring, callous, or thickheaded. Watch out for negative emotions in yourself--especially feelings of victimization, competition, enmity, or judging from yourself or perceived in others.
