I leave it at home when I go to work in a high security area and I realise that these journeys are totally different to others. I have no bus app to see when the bus is coming, I just sit and wait. I have no phone games or messages to answer, I am out of touch with the news for hours at a time.
These days are a lot more peaceful, I sort of like it. Sometimes I am bored and twitchy. But mostly it is fine
