Suppose some boys are playing football in the field. While going to the market, I see my brother standing beside the field and watching them playing. So at this moment,
- what am I supposed to ask my brother?
a. Why don't you play?
b. Why are you not playing?
- Do the examples above carry the same meaning and can be used interchangeably?
- If not carrying the same meaning, then in which situations could I use them?
