You can find someone pretty or not, so what? Some people are better looking than others.

Be honest if you want to uphold integrity, even when you did something wrong. Now, for traffic violations, there can be a justified reason, as many are there to prevent people from engaging in behavior that increase the potential to harm others. Speeding has that potential, but some speed limits are a joke.

Lying to to the embodiment of something wrong is doing something right, as the wrong will nail you for not adhering to something wrong. Admitting we did something in a deluded system can mean we get punished fro not doing anything wrong. Smoking cannabis for instance. Lie to the evil empire, and prevent yourself from being swept up in its madness.

Qualified for a job? If you aren't then don't make shit up. Be honest, don't lie.

In general, don't lie. It's obvious. Yes there are nuances to understand.
