The short answer
A joke me fez rir, while good news me deixou feliz. Fazer plus an action and deixar plus a state both explain a reaction, but their complements differ. Learn the cause, the person affected and the result as separate parts so you can describe an effect without making the experiencer the cause.
Start with the situation
Original written teaching examples, not transcripts or new recordings
Use fazer someone plus infinitive for a caused action
Fazer can introduce an action caused in another person: me fez rir, fez a criança chorar. The subject is the cause, while the person affected appears before the infinitive or as a pronoun. The infinitive names the resulting action. This does not always imply a deliberate attempt to cause it; a scene can make you laugh even when nobody is trying to entertain you.
A piada me fez rir.
The joke made me laugh.
O barulho fez o bebê acordar.
The noise made the baby wake up.
Use deixar someone plus adjective for a resulting state
Deixar followed by a person and an adjective can describe causing or leaving that person in a state. A notícia me deixou feliz presents the news as the cause and happiness as the state. This differs from deixar someone fazer, which can mean let or allow the action. Look carefully at whether the complement is an adjective or an infinitive before translating deixar.
A notícia me deixou feliz.
The news made me happy.
Make adjective agreement follow the affected person
In a state-result sentence, the adjective describes the person affected. It therefore agrees with that person where the adjective has different forms: nervoso or nervosa, animados or animadas. The cause may have a different gender and number. A male speaker affected by feminine notícia still says me deixou nervoso, because the state belongs to him rather than to the news.
A espera deixou as crianças cansadas.
The wait left the children tired.
Separate causing an effect from allowing an action
Ela me deixou falar can mean she let me speak. Ela me fez falar can mean she made or caused me to speak. The difference can be substantial when describing pressure or permission. Do not replace one verb with the other merely because both are followed by a person and another word. Identify whether the second part is an allowed action, a caused action or a resulting state.
Ela me deixou falar, mas não me obrigou.
She let me speak, but she did not force me.
Describe the effect without assuming intention
When you tell someone that their message left you worried, you describe its effect, not necessarily their purpose. Add sem querer or explain that you understood a detail differently if intention matters. For practice, pair one cause with an action result and another with a state result. Keep the experiencer explicit, then check the adjective ending only in the sentence that uses an adjective.
Sua mensagem me deixou preocupada.
Your message left me worried.
Try it with your own words
Say or write a Portuguese answer before opening the suggestion. Other natural answers can work; compare the meaning and situation, then read the explanation.
Original practice: A funny scene caused you to laugh.
Show a possible answer and explanation
A cena me fez rir.
Fazer introduces the caused action rir. You are the person affected, while the scene is the cause.
Original practice: Good news made a female speaker happy and excited.
Show a possible answer and explanation
A notícia me deixou feliz e animada.
The adjectives describe the speaker. Animada agrees with her, while feliz has the same form for masculine and feminine singular.
Original practice: Someone permitted you to finish, without forcing you.
Show a possible answer and explanation
Ela me deixou terminar.
Deixar plus infinitive expresses permission in this context. Me fez terminar would introduce a causative meaning instead.
Original practice: The long wait left two boys tired.
Show a possible answer and explanation
A espera deixou os meninos cansados.
Cansados agrees with the boys experiencing the state. It does not agree with the feminine singular cause, a espera.
