The context of the following conversation is Jessie asked them to tell the time but they had no watch so they looked at the sun.:
Casey says I had to make it home by 6PM so I could cook dinner for my family but didn't know the time.
The friend responds Yeah, you never bring your watch with you..
Casey responds So I thought in that case it's better to take a look at my phone. Surely that can function as a clock/watch..
The friend responds But you left that at home too?.
Casey responds What? How could you know? People practically live with these things now a days..
The friend responds I'm sure you could still spend that nice day looking at the sun and the scenery. And I know in the end you used the sun to get anc estimate of the time..
