Hello everybody!. I am eager to understand at least the difference between to + infinitive and for + gerund in some cases, for instance as in the next case: "They gave her directions to prepare the party" "They gave her directions for preparing the party" Sometimes I believe to see some difference but it is clear that I don´t understand it well. Can we really use both type of forms in all the cases. though,i suposse, with some difference of meaning? Thank you very much anyway!!
