Nothing is a line
There's this quote from Succession that still lingers. Even if it's years since I watched the third season. (The quote appears in the fourth episode of this season.)
Siobhan is talking with her father, telling him that she thought there were some absolutes. Some lines that he wouldn't cross. To which Logan Roy responds:
"Nothing is a line. Everything, everywhere is always moving. Forever. Get used to it."
How I often I forget this lesson. Everything, everywhere is always moving. Forever.
