I have always taken the approach with ground dwellers who want to "prove" they are more comfy in a tent, that I am happy for their comfort. I emphasize the importance of comfort and extol the virtues of a night of great sleep.
When I get up and sit up in bed and see the morning, they view my world a little differently. When I stand up rather than crawl on the ground to pack, they view my world a little differently, and most of all, when I pack in a hard rain, standing up, dry bedding, dry hammock, they view my world very differently.
Just enjoy it, you have nothing to prove. The pleasure of your experience is what counts, and if your ground dwelling friends are at all perceptive, they will understand your smile and cheery disposition, all the while you are standing, sitting, or reclined in your hammock, never on your knees, never on the hard cold ground.
