My question is about the use of the use of the auxiliary verb "avere" with "piacere". I have always been taught to use "essere" but a book teaching "piacere" using "avere" has been brought to my attention.
I am including a link to the book on Amazon https://www.amazon.com/LL-Italian-Conversational-Approach-Verbs/dp/0517885301. I've tried to copy and paste the page sent to me, but that doesn't seem to work. Below, is a partial "copy" of the page.
103 piacere to like, to be pleasing
ho piaciuto abbiamo piaciuto
hai piaciuto avete piaciuto
ha piaciuto hanno piaciuto
It shows the present perfect as
ebbi piaciuto avemmo piaciuto etc.
