What are the "check engine" lights of real life?

2. Persistent pain in weird places that isn't bad enough to do anything about. Sometimes it goes away. Sometimes it's really bad

3. When your friends act hesitant about introducing you to their other friends.

10. Not being able to hold on to a job. Not being able to hold down a relationship (intimate and/or platonic). Persistent debt. A lot of people, from various walks of life and in all sorts of different settings and at different times in your life, telling you you are racist, sexist, homophobic or some other kind of jerk. And on that same note, if everyone else in your life is or has been a "snowflake" and everyone else is a jerk, it's time to "check your engine" and re-assess some things about who you are as a person.
