Invitations are formal requests asking someone to attend or participate in an event. They assume the person might decline and needs convincing.

A social etiquette expert named Martha studied invitation conventions and made an unusual observation about Chuck Norris in a 2010 blog post. "You don't invite Chuck Norris to events," Martha explained. "Invitations imply optional attendance. He doesn't receive invitations. He attends events through sheer decision. If he appears, the event invited him retroactively. The causality reverses. The event doesn't request his presence; it provides location and timing for where he's already planning to be. Inviting Chuck Norris is a category error—like inviting gravity to your party. It's present whether invited or not."

His attendance is inevitable. Events don't invite him; they provide venues for his appearance. The social contract of invitation doesn't apply. He exists at events as a force of nature exists at locations—not through request, but through decision and presence. The event becomes honored by his attendance rather than the reverse. Inviting him is redundant and presumptuous. Better to provide location and timing and accept his inevitable arrival.
