It is an abstraction. It means whatever you need or want it to mean in a given moment. I would do a thing like this while thinking of my loved ones that may be visiting; to make them think; to give them a figurative hand on the shoulder; a meaningless aphorism of solidarity and human empathy. It may be of no value to a person that struggles with abstraction, or even my younger self that struggled to contextualize my own. I have learned to value the little things, especially the few people with a genuine capacity to care about others. This message was likely a reaching attempt at such a caring kindness of compassion and love.
