Two. The night

It is worse at night and it is worse in bed, and neither of those is a coincidence.

Tired people compare badly. The tolerance for an unflattering thought about yourself drops with sleep, which is why the same post is a shrug at nine in the morning and a verdict at midnight.

And a phone in bed makes the last input of your day a stream of other people's best hours, delivered to you at your least defended. Nothing about that is a moral failing. It is a bedroom layout.
