Here is a problem that I am having trouble with. You're help would be most valued.
A: I'm going to buy Ellen a red hat.
B: I wouldn't, if I were you.
A: Why not?
B: She isn't going to like/She might not like the color red.
The answer is 'She might not like the color red,' but why can't we choose 'She isn't going to like the color red'? Both sound right to me.
You need more context.
Maybe it is not allowed for B to know the future.
If B can't know the future for sure, and if he wants to be sincere, he may think it is wiser to leave it open. She might not like ... is (just) a possibility.
