Imagine I told you something like:
If you don't reply for the next 3 hours, I will stop talking to you.
What would you think the meaning was? Do you think it would be
- If you don't keep replying for the next 3 hours I will stop talking to you. or >- If you don't reply sometime between those 3 hours, I'll stop talking to you.
Is it just a matter of emphasis? E.g.:
- If you don't reply for the next 3 hours, I will stop talking to you.
- If you don't reply for the next 3 hours. I will stop talking to you.
