Are these sentences correct:
1) There are things that you cannot do and not tell your family that you've done them.
2) There are things that you cannot see and remain the same person.
3) I did something that no man can do and remain the same.
4) I did something that when a man does is, he is changed forever.
Gratefully,
Navi
Hello, Navi—The only one that is totally ungrammatical is (4), and that's probably because you intended to type "it" where you typed "is." However, I dislike all the examples and strongly prefer these revisions:
(1a) There are things that you cannot do without telling your family that you've done them.
(2a) There are things that you cannot remain the same person after seeing.
(3a) I did something that no man can remain the same after doing.
(4a) I did something that changes a man forever when he does it.
