alosso:
To me, "I think" is but a statement of private opinion, nothing conclusive can be extracted.
Like when the mods officially state "I believe...".
Either you know, or it's void.
In this case, I know, and I confirmed.
As I stated, when used with an object you are quite correct. However:
think : verb (used without object), thought, thinking.
1.to have a conscious mind, to some extent of reasoning, remembering experiences,
making rational decisions, etc.
We are getting a bit off topic though, I think.
