what to get someone for christmas that has everything

That can be a tough one. I would suggest thinking about what your friend's passions and interests are. Does he enjoy sports or outdoor activities? If so, you could get him a new piece of equipment or gear. Does he have a favorite book or movie? You could get him a signed copy or a collectible. Alternatively, you could consider getting him a donation to a charity that he cares about, which would not only show that you understand his values but also have a positive impact on others.
