It doesn’t necessarily have to be about a trip you took. It could be about anything, even something you feel you were specifically asked about. Do you think the people who ask you about those things really care about the things you care about the same way you do and so they want to hear everything you have to say? Maybe they do, but it’s really very rare for people to care about things the exact way anybody else does.

Just because somebody asked doesn’t mean they care about the thing. A significant majority of the time people ask, and then actually listen, it’s because they care about you, not any particular thing. And those people probably like to be heard just as much.
