Subjunctive

[Robert Pinkham]

Does one use the subjuctive after " depuis que" ?   -- depuis que je parlerais la langue?

[Erwan]

I think we can't use subjonctive after "depuis que" for the same reason we should not use it after "après que" (even though you can often hear the subjonctive with the latter).

As the action or the fact you're talking about is realized you have to use an indicative tense .
