I Don't Care
A common, slightly informal way to say 'It's all the same to me' or 'It makes no difference to me'.
Use this when you mean 'I'm not interested'. It's more about a lack of interest than a lack of preference.
An indirect way to show you don't care by leaving the decision to someone else. It means 'Whatever you want' or 'As you wish'.
Do you want to go to the movies or the park? — Honestly, I don't care.
We can have Chinese or Mexican food for dinner. — It's all the same to me, I like both.
They always talk about soccer, but I'm not interested.
Should we leave now or later? — Whatever you want, I'm ready.
'No me importa' is the universal standard. 'Me da igual' is also extremely common and understood everywhere.
You will often hear 'Me vale'. Be careful, as this is very informal slang and can sound dismissive or even rude depending on the tone and context.
'Me da igual' is arguably more common than 'No me importa' in everyday casual conversation. They also use the verb 'pasar' informally (e.g., 'Paso de ese tema'), meaning 'I'm skipping that topic/I'm not dealing with that'.
In addition to 'No me importa', the phrase 'Me da lo mismo' ('It gives me the same') is very common, functioning just like 'Me da igual'.
Using 'No cuido' — A common error is directly translating 'care' as 'cuidar'. 'Yo cuido a mi gato' means 'I take care of my cat'. For opinions or preferences, you must use 'importar'. The correct structure is 'No me importa'.
Saying 'Yo no importo' — This sentence translates to 'I am not an important person'. The verb 'importar' works like 'gustar'. The thing you don't care about is the subject, and the person who doesn't care is the indirect object ('me'). So it's '(It) doesn't matter to me': 'No me importa'.
Using slang in the wrong situation — Phrases like 'Me vale' (Mexico) are very strong slang. Using them in a formal setting or with people you don't know well can be very rude. Stick with 'No me importa' or 'Me da igual' to be safe.
