After getting enough bait, Abraham then chose to fish on the embankment behind his house.
This is because, after Abraham climbed up and observed the situation in front of his yard, Abraham realized that the water monster was still visible spreading around the front yard of the house.
Even though they had walked quite far, if Abraham insisted on fishing in that area, he could imagine that.
Most likely it was not the fish that he would get, but the water monster that could be attracted to his fishing rod.
So to avoid unnecessary problems, Abraham of course wanted to try fishing in an area where there were no water monsters.
And from his observations, he saw that the area behind his house did not have any water monsters.
Seeing this, of course he was happy and decided to fish there.
Although, he also understood that you are always likely to get disturbed by water monsters.
But he put that aside and chose to try fishing first.
