What you tolerate from friends at sixteen tends to be what you tolerate from bosses at twenty-six.

You are setting your own baseline right now without meaning to. Whatever becomes normal stops registering: being spoken to a certain way, always being the one who gives ground, having your time treated as free. The calibration you pick up among friends is the one you carry into rooms where the other person controls your hours and your pay.

Pick one thing you have been letting slide and say something about it this week, plainly, to a friend. It will feel out of proportion. It is practice, and learning the sentence now is far cheaper than learning it from a manager.
