I have asked so many question about use of Had (Past Perfect) in English sentence. But sometime after I made my concept clear come across some sentence which force me to re think it.
"He had come to my residence and I am grateful to him for that. Both families share a very cordial relationship."
Similarly can I use Perfect Tense for below scenario / Context.
One of my colleague came to me to discuss some issue. we discussed it and he left. after 2 days we discussed it with other team member.
To report whatever discussed earlier can I start my conversation as below?
"Mr. Xyz had come to my desk to discussed about xyz issue. We discussed it but now we want a solution from you also."
Whenever I asked this type of questions I was asked to use Simple past instated of past perfect. But when I read similar contexts in past perfect I get confused. Even some of the article I read while reporting use of Simple Past and Past perfect is optional.
