the opening of an envelope
Any event, celebration, or ceremony, no matter how trivial or unremarkable, that one attends purely for the sake of visibility. Often said in relation to celebrities or media personalities who make a point of attending anything that will give them more public exposure.

With the way she carries on, she'd even go to the opening of an envelope!
