Can't look thin anymore (Patreon)

You're inviting your former high school best friend to visit and realize he must have gained at least 60lbs since his twunk days, and it's especially shocking when you get a glimpse of his belly protruding out of his shirt as he brushes his teeth, or as he clenches his butt while peeing but it still looks much wider than it ever was...
Would you say anything? What would you do or tell him?
