We can use "for...to" construction with many adjectives.
I am happy for you to be admitted to college.
I am glad for you to have finally found a job.
I am willing for you to go ahead and try it.
I am honored for my son to receive the award.
So I thought this construction can be used with EVERY adjective that can take to-infinitive as an adjective complement. But it doesn't seem like it.
*I am sad for you to do it.
*I am afraid for you to try it.
Even though these two adjectives can take to-infinitive as an adjective complement, it sounds strange when I use "for" to introduce a new subject of the infinitive.
Why can some of the adjectives have "for...to" construction and introduce a new subject of the infinitive while the some can't? And is there a category of adjectives that are able or prohibited to have this construction?
