Translation:Es importante amar a los abuelos.
Where does “your” come from? Why wouldn’t it be just “grandparents” or “the grandparents”. What in spanish let’s us know there is a relationship?
There's no relationship, it's just the way you speak in English, where you use the pronoun 'you' as impersonal, like I just did.
Why is los used here instead of tus?
It's an impersonal statement. English tends to use 'you' (instead of 'one') to speak impersonally.
Thanks. That makes sense.
