💡 Grammar Points

Remember, 'estuvieron' comes from 'estar,' which describes temporary states. If you used 'fueron' (from 'ser'), it would mean their condition was permanent or inherent, which is usually incorrect for feelings like sadness or tiredness.
❌ Common Pitfalls
Using the wrong verb for temporary states
Mistake: "Ellos fueron cansados."
Correction: Ellos estuvieron cansados. (Use 'estar' for temporary states like tiredness.)
