I'm a bit familarized with conditional sentences. But the following sentences with 'should' and 'happen to' are quite confusing too me. They are:
- If it should rain, I will stay at home.
2.If it should happen to rain, I'll stay at home
- If it happens to rain, I'll stay at home.
What are the meaings of those sentences ? Do they all mean the same ? Thank you a lot in Advance for your answer.
