Some people stand.
Some people sit.
Both are allowed.
Standing may be painful, unsafe, inaccessible, or simply not possible. Nobody owes the section an explanation.
If you are standing or dancing, enjoy yourself—but read the room. Stay in your space, protect accessibility areas, and do not spill beer, crash into the row behind you, or windmill like you are fighting bees.
If you are sitting, sit. Rest. Observe. Become one with the cup holder.
Just remember: a seat number does not guarantee everyone around you will remain seated and emotionally contained.
Standing is allowed.
Sitting is allowed.
Dancing is allowed.
Pretending nobody else exists is the actual concert crime.
