Rotten egg smell is like that one friend who always shows up uninvited. You have to lock the door. Pour bleach down the drain monthly. Run hot water regularly. Replace the water heater anode rod every few years.
And for the love of all that is fresh, don’t ignore the first whiff. That tiny smell is a warning. It’s the universe giving you a high-five before a low-blow. Act fast. Your nose will thank you. Your dinner guests? They’ll think you’re a domestic god or goddess. Now go—conquer that stench. You’ve got this.
