Hello!
I'm a 17-year-old Polish student who is constantly becoming more and more interested in foreign languages.
Some time ago I became aware that both options (I mean what I included in the subject line:) are equal. Then I decided I wanted to find the difference - even the slightest possible

And it seems that it is so - even some Australian educated native speaker couldn't tell me what the difference was. Bywater in 'Proficiency Course in English' also doesn't point to any difference, mentioning only both options are equally correct. But I still bet there must be some diffrence - otherwise what would this distinction be for?

Could anyone explain this bothering me matter?

Huge thanks in advance.
PS. Fell free to correct me everytime I make a mistake - I want to be stylistically correct too
