As/When I was going out, it started to rain.
Do 'As' and 'When' both work well for the sentence and sound natural to native speakers ?
Thank you in advance.
It seems to me that the difference between them is,
'As' emphasizes the movement of leaving to go out
'when' emphasizes some point during the action of going out.
And basically, I can use "as" here in that it doesn't have the implication of the meaning of "because".
What do you think of it?
