Simple past and past perfect are so confusing...
Please tell me if any of the sentences below make (or makes?) sense:
1) She had already opened the package before I had the chance to tell her not to.
2) She had already opened the package before I could tell her not to.
3) Before I could tell her not to, she just went ahead and opened the package.
4) (I wrote this in my question below) I was worried that I might have sounded stupid.
Are simple past and past perfect interchangeable?
