Will parents recognize their children in Paradise, and how will they interact and converse?

The questioner is advised to focus on knowledge that benefits them in this world and the hereafter. As for how the people of Paradise interact and what they talk about, it is mentioned in a Hadith by Tirmidhi and Ibn Majah that the people of Paradise will recognize one another. There will be a marketplace in Paradise which they will visit every Friday (according to earthly days), where their Lord's Throne will appear to them and He will manifest Himself to them in a garden. They will sit on various pulpits, and Allah will address them. Then a cloud will come and rain down pleasant fragrances upon them. After that, they will go to the marketplace of Paradise, which is surrounded by angels, and it will contain all that souls desire. There, the people of Paradise will meet one another and their beauty will increase. Upon their return, their spouses will welcome them with something even better than what they had left them with.
