The sadness you feel after a tv show or movie takes a time skip.
You feel sad because you don’t get to witness the years skipped.
Friend: Did you watch the movie?
You: Yea, I feel the time skip sadness. I wanted to know what happened in between.
Friend: I feel you.
In movies or stories, a 'Time Skip' is a narrative device where the story jumps through time
"The last chapter had a ten-year time skip, and suddenly everyone was having kids, mortgages and unpaid water taxes"
