Everyone’s a team player when the bus has AC. Watch who stays positive when it breaks down in July.

Comfort hides character because it never asks anything of it. Good conditions let almost anyone be pleasant, which is why little is revealed until something goes wrong and there is genuine discomfort to absorb. People who stay decent in the heat are not a different species; they decided in advance that this part counts too.

Watch yourself the next time something is delayed, broken, or uncomfortable. Notice what your first sentence is and who it lands on. Choosing the useful remark instead of the bitter one is a small discipline with a long reach.
