We need a word for the feeling of frustration, impatience, and impotence that sets in when everyone else has seen the movie / read the book / experienced the experience, but you haven’t yet, and so you’re forced to put off reading and/or engaging in the discussion until you have also seen the movie / read the book / experienced the experience. It’s a feeling that’s accentuated when you’re determined to avoid spoilers prior to engaging with the whatever-it-is yourself.
So, yeah, Narnia. I’ll get there eventually.
UPDATE: Many suggestions in the comments. I cannot choose among them.
