Why «как напьётся» аnd not «когда направился»?
Here's the bit of dialog I am asking about:
– Это кто тебя так?
– А, муж. Как напьётся...
I would translate the first part as:
– Who did this to you?
– My husband.
And then "When he was drunk", but it looks like the future tense is used? What does that last line mean, how does the grammar work?
