I often hear this take, but I think it's overly simplified. It’s completely acceptable to respond in a negative fashion to ‘how was your day’. People just don’t want details.

So, “Stressful” or “Annoying” is fine. But “I had this one customer who…” is not.

The only real lie is optional and it's mostly about how you want people to think of you. If 10% of the time you’re slightly unhappy that's considered reasonable, but if your unhappy 90% of the time people don't generally want to be around you.
