ANALYSIS OF "SHOULD"

As I am not a native English, I wonder about "SHOULD". It means "MUST" or "HAVE TO".

So I confused which one the meaning of "SHOULD" is. It sounds like slight "MUST", but basically it is softer meaning than "MUST". I wish to meet someone who can explain the analysis of "SHOULD" on grammatically.

By the way, The point of this essay is not about "SHOULD".

Almost three days passed, after I started to have this INDIAN JOURNEY which means Curry life. I got concern that perhaps my useless essay have been read by only five people. Yeah, that guy, that lady and that... I can easily imagine who reads this. This tragic fact makes me reduce my motivation to write this blog.

I needed to drum my blog up to my curry friends, because nobody read this curry, tried to force my friends to read this curry.

"Nice Picture on its title is!"

This word is from my friend... Come on...
That picture is sponsored by H.I.S which is Japanese travel company. It is not my work. When it made me disappointing, I realized my big mistake that I had only Japanese blog.

This is why I SHOULD have this English version.
