The dog, Duke, would either stand still as a post while Hooper was on the ground, to urge him to get up and continue trying. Or he would do something completely different - he would walk faster and faster, which in turn made Hooper walk faster than he used to, which eventually affected his endurance and stability positively.
Chronological means, verbatim, "(<span>of a record of events) starting with the earliest and following the order in which they occurred". So what events are you writing about?</span>
It means that if you do not speak up about being depressed or "in pain" people around you that you interact with will unknowingly kill you on the inside and when/if you speak up they will assume you enjoyed it because you did not speak up before. Its a metaphor you see... if someone were to continuously stab you and you didnt speak up, they would stab you to death and assume you liked it for not acknowleding your pain. (excuse my terrible grammar im using an uncomfortable tablet with no auto correct and am trying to type this fast.)
Maybe your brain is like, you're so right you outta be left. LOL
