There are obviously some adults who have severe limitations on their ability to socialise and nobody is implying they are lazy.

But a wider social scene I have been part of has people with evident learning difficulties, people with obvious neurodivergence, people with physical disabilities.

If you show up and show interest in sharing a common goal with a large enough circle of people, then those people will find you a way to participate at your own speed.

If you have a way to show up for social activities, or assistance to show up, you could show up, you have a desire to show up, and you don't show up... some of that really is laziness at worst and avoidance at best.
