Past perfect and present perfect

Hi,
If it takes more than 5 minutes trying to think of a scenario where both perfect tenses are used, than I suggest not waste time on it. By the way, we appreciate questions posted with proper capitalization and literal English.

Thank you for your advice but my curiosity hasn't been satisfied.

Beata KolasinskaI just would like to find out if is possible to use both past perfect and present perfect in one sentence ? if so , please give me an example please

Have/has + had constructions are relatively rare, but it is possible:

She has always wished (pres perf) that she had been (past perf) born a boy.

AnonymousShe has always wished (pres perf) that she had been (past perf) born a boy.

That is perfect, but like you said; " rare". I would say this is a border-line sentence of the counter-fact nature, or conditional. I didn't mean it was impossible. What I meant was, if we had to think hard for a scenario in which to apply the both tenses, then it is not commo

I see that it's better to avoid that combination.
Thank you for your help.
