somewhere vs anywhere

[Mdenglish]

What is the difference in meaning of the following questions?

1. Did you go somewhere?
2. Did you go anywhere ?

Thanks in advance

When you ask the first question you are think that it's quite likely that the person went somewhere. When you ask the second question you think it's rather unlikely that the person went anywhere and you probably expect a negative answer.

1. Did you go somewhere? = I guess you went somewhere. Is that true?
2. Did you go anywhere? = I know nothing about whether you went anywhere or not. Can you let me know the fact?

Just my two cents.
