Yes. For me personally, I found the framing that “building and maintaining friendships takes time, energy, and sacrifice, but is so totally worth it for our healthy wellbeing,” very helpful to inspire me to focus on the kinds of relationships I want and justify the investment to be a better friend.

GP’s comment is a wry (“hobby”) and pithy and provocative take that’s not wrong. IMO, friends are the nutritious meal that’s more expensive than friend substitutes. GP seems to have a different conclusion on cost/benefit. But nobody can deny there is a cost!
