What do we do?

There is an imprint of our lives wherever we go, Whatever we decide to do with our existence impacts everything we come into contact with. There are consequences for each and everyone of our actions, yet we continue living, like our perspective is the absolute. What happens when none of it makes sense anymore? What happens when, maybe it still makes sense, but the reality isn't something we really want to have to think about? What if it never really meant anything at all? Where is the punchline? What is it that we do, When we don't find it funny?
