There are things that I do not comment because they are very personal but:

1. It was very dark and the place where I live is very dangerous, so my friend should not go alone.

2. Hours before, his son made a sign to me indicating that he should watch over his father and take him to his house when he left.

3. He was the one who fought, I simply left him at the door of his house, and waited for him to enter.
