"I bought apples." vs "I bought some apples."
Is the first sentence grammatical? If yes, is there any difference in meaning between the two?
Somehow I feel that if I am asked "What did you do yesterday?", "I bought some apples" sounds better than "I bought apples". Am I mistaken? On the other hand, if I am asked "What did you buy?", then "I bought apples" sounds fine to me.
