I read this question The correct usage of bring vs. take
Andrew said
Which verb you choose reflects what point-of-view from which you imagine the movement. If you picture yourself already at the church, then you can use come. If you picture yourself at another location, moving toward the church, then you use go.
In the same way bring feels like you are coming with the person to the place you want to be.
My question is
How does the speaker imagine the location when choosing "take vs bring"?
I guess the imaginary location is the important place that the sentence focuses on or emphasizes. The place where the speaker is standing might not be the important place.
Say, a dad and son is at home now.
There are 2 scenarios.
The first scenario is that the dad is about to take his son to school in his car
The second scenario is that the son is about to go to school alone.
When does the dad say to his son "don't forget to take the bag to school" and "don't forget to bring the bag to school"?
I guess in both cases, the dad would say "don't forget to bring the bag to school" regardless the location where the dad is standing. That is because the dad imagines "the school" is the important location not "the house".
