Hello! I'm looking for answer on the question above. I saw it a lot of times but I've never been understanding it. Asking for the people with knowledge of this. Simple: Where? When? Why?
I'm just learning English so I very need a practice. If somebody is involved too, I would like to talk to you for any topic. You will correct me, me too. :)
"have had" and "had had". Where are using?
