"Everything that goes up must come down. But there comes a time when not everything that's down can come up"

This quote by George Burns is a pointer that in life, everything has its ups and downs. Much like how things that are tossed up into the air will ultimately come back down, our situations and emotions also have their low and high. Nevertheless, there might come a point where not everything that is down can be brought back up. This could refer to scenarios or people that have actually reached a defining moment, where the damage is permanent. It functions as a caution to value the great times and to be mindful of our actions, as not everything can be fixed or altered.
