The common analogy for a push down stack is the stack of dishes at a buffet. Take one off the top and the next one pops up.
That is like what it has been for me lately. Do one critical task, the next one pops up. Work like crazy to try and get the stack down, but it just keeps getting reloaded. Maybe that is just life.
This has been a good week. I popped up a lot of dishes.
