"生日是最糟的日子，现在我们口渴时喝香槟"

Simplified Meaning:

When the person was younger and life was tough, even special days like birthdays felt bad because they didn't have much money or nice things. As they grew older and their situation improved, they started enjoying life more, to the point where they can now afford luxuries like champagne. This transformation from hard times to better days highlights the change in their fortune and living conditions. For example, think of someone who struggled financially when they were young, maybe living in a small apartment with very basic amenities. They couldn't afford any treats, even on important days like birthdays. Over time, through hard work and maybe some luck, they got a good job, earned more money, and moved to a nicer place. Now, they can afford to enjoy finer things, like nice dinners and drinks whenever they want, not just on special occasions. This change shows how perseverance and improving one's situation can turn difficult times into a more comfortable, enjoyable life.
