After age 21, I don't have a problem with people getting excited about "landmark" birthdays. The turning of another decade really does tend to mark the start of a new phase in one's life. I'm far more annoyed with adults who go on about their "birthday week" or "birthday month" every damned year.
But Polissa's life, which never was going to go much of anywhere, skidded into a ditch about a decade ago, and has been sitting there, an unrecoverable wreck, ever since. There are no big milestones in an idle, stagnant life. Even getting her uterus yeeted didn't signal the end of a cycle and start of a new one.
Polissa's 40s will not be much different from her 30s (other than the continued decline in her health), because she doesn't do anything. She has no social, economic, or familial role that she will mature into as she ages. She's just a fat lump that, apparently, even her own family barely tolerates, and only because if they don't she'll end up living on the street.
So frankly, it's rather stupid that she's so excited about turning 40. But given that she has pretty much nothing else to celebrate, and no other means to be the center of attention that are positive, she might as well wring whatever she can out of it.
