Warning: Sink hazards are real and they will ruin your day.
Don't stick your head in the sink to check if the water's safe. It's not a science experiment.
Prevent the spread of germs. Your sink might be a petri dish.
Also, don't lick the dishes.
Don't just use hot water. That's not how you clean things. Use a mix of hot and cold. It's like Goldilocks.
Unless you're a toddler. Then it's just Tuesday.
Or, you know, if you're just generally careless.
You might get lost in your own reflection. Or, you know, see the face of the devil.
You might fall in. Or, you know, just get wet.
