People need widgets in order to meet other people. The widget can be a dog, a beer, or a coffee, anything that increases the likeliness of people talking in a social setting. People feel more confident and more engaged when they’re holding on to something and have a reason to be there.
It’s easier meet new people when we’re younger because there are simply more free time and more opportunities: at school, in organized sport, clubs, and countless other extracurricular activities.
