Social Anxiety in a nutshell if you know how to read between the lines. We see this intro and outtro as nice and warm, but the middle is the chaos of what happens in the mind of someone with social anxieties. The family doesn't really say these things about him, it's what he percieves the family thinks about him. "Look who finally left their room" is probably the only real statement made, but only as an innocent joke. The rest is an internal chain-reaction of anxiety as the chaarcters onterprets that as an assault to every single flaw he thinks he has. Pretty Genius if that's what the author meant.
