It’s not that people don’t expect life to change, it is the way that change comes about that always catches them unprepared. Sometimes it is as trivial as rain on the day of the picnic that everybody had spent months planning and looking forward to, or as significant as a shift in circumstances that makes one’s life plans lose consistency, but these are things that people usually adapt to, that they talk about with their loved ones, and then, after sufficient time had passed, they put behind them and move on.
Other changes can’t be assimilated gradually, because they just don’t fit in the general understanding of existence, and they put a kink in the smooth passage of time, a singularity of sorts, that divides life into before and after. The reality of the plant belonged to the second category, and no amount of commiseration could make it blend gradually into the fabric of life.
