1. We can stay here for the evening.
I'd rather not. It's only a few more hours (of driving).

2. I may be in California next Monday.
Well, let me know what you decide.

3. She might not make it to the wedding.
That's too bad. I hope she feels better soon.

4. We could go (and) see a movie.
Or we could go out for ice cream.
That would be fun.
