I need your help. Could you please tell me which one of these is correct?
A. I'm going out to the garden to pick some beans for it's not raining.
B. I'm going out to the garden to pick some beans while it's not raining.
I assume that the first one is correct, because for in this case has the meaning of "due to the fact that". Please tell me what you think about this. Your answer will be greatly appreciated. Thanks a lot in advance.
