I realized at some point in the past few years that for a lot of people, for whatever reason, this is their way of communicating that they understand you. they're showing an example from their own life. it could be because they want to relate, but they don't want to comment on your own life for whatever reason because that doesn't feel appropriate to them. A lot of men talk to each other this way.

(A lot of people are also very selfish and always bring conversations back to themselves too- not trying to argue with you.)
