He realized that he did not

walk into people on the street.

He realized that such a break was too difficult to endure. That is the reason why he relapsed. 

He realized he was too much dependent on his smartphone and could never benefit from a digital detox. 

He realized that it was glorious on the other side.

He realized that he could actually enjoy food without sharing the enjoyment.

He realized that a permanent disconnection was the best possible option left if he wanted to improve his mental wellbeing. 

He realized how much

time he wasted trying to think of things to say.
