Is it common to use future tense after subjunctive conjunctions of time?

Question

I've read that many people that speak spanish sometimes don't use future tense when people that speak english normally would. So I was wondering if the future tense was used commonly with the following example.

• For example with "cuando"

"Cuando llegue david, comeremos"

"when david arrives, we'll eat"

• With "tan pronto como"

"Tan pronto como david haga la tarea, iremos a casa"

"as soon as david does the homework, we'll go home"

Or would people commonly use "comemos" and "vamos" instead?

Answer 1

Now that you say it I've noticed that indeed I never use the future tense.

I'd have said: Cuando David llegue, comemos. Tan pronto como termine la tarea, nos vamos a casa. Maybe this varies for other native speakers, I also think it depends on the country they are from. For instance, here in Argentina (Buenos Aires) we never use the present perfect. We wouldn't say: he llegado a casa, but llegué a casa. No matter the circumstances, we always use the simple past. But this tense is used by other regions, so maybe it's the same in this instance?

Answer 2

The present simple tense in Spanish has a lot of nuances unlike the present simple tense in English.

• We use it to replace an action in progress: ¿Qué haces? Instead of ¿Qué estás haciendo?
• With offers: Ya no quiero comer esto. — Yo me lo como. Instead of saying Yo me lo comeré.

There's nothing wrong with this usage.
