A phone call

1:30a.m.
A man started walking alone in the bush.
Indeed he should be sleeping after trekking for the whole day.
But he kept walking...
An hour later, he was finally there..
A place where there is reception for his cellphone..
He called her.
He talked with her for less than 10 mins.
After that,
He had to walk for an hour to get back to his camp.
