As people get older, do they argue less with their friends?

I think it depends on the kind of friendship. With old friends from childhood, people often argue less because they've known each other for years and understand each other's personalities - like my childhood friend Li Wei I mentioned earlier. We rarely had serious arguments because we'd already been through so much together. But with newer friends, even older adults might disagree more often, especially about lifestyle choices or values. I've noticed this with my parents - they have some long-term friends where everything's easy, but newer acquaintances sometimes lead to debates about things like parenting styles or technology use. That being said, older people do tend to pick their battles more carefully.
