Slang of the Day

De noche todos los gatos son pardos
Appearances can be deceiving
Normal que te confundieras; de noche todos los gatos son pardos.
After a party, someone realizes they mistook a stranger for a friend in the dim lighting.
Literally, it means "at night all cats are brown/grey."
In practice, it means that in the dark (or with limited information), differences blur and appearances can be misleading. It's a traditional proverb, more old-school than slang, and it can apply to looks, judgment, or moral choices when conditions hide details. People use it to warn you not to trust first impressions or to explain why someone made a mistake.
"De noche todos los gatos son pardos" does not mean we all struggle with the same problems, the night is a good counselor, small problems grow worse when you ignore them. It specifically means "Appearances can be deceiving".
