Sometime, people put a question mark at the end of a sentence and use it to ask something. Instead using an interrogative sentence:
Do you like it?
You like it?
I think it is more often to someone who is not good at English.
As I am Korean, however, I realized that I also often and frequently violate Korean grammar. And I can't keep that all.
So, my question is:
- Is it common for the native to use a declarative sentence as interrogative?
- Is it hard to understand in a short time?
- How are your societies tolerant to this?
- Is this regarded as impolite or rude?
