I have been participating in POB WOTW for 4weeks now, I wanna thank @calumam for the privilege and for the good topics.
I would like to say causality is cause and effects while cause and effects make up things. The combination of the two shows results and also predict the outcome.
The making or starting of something can be hard, but when is done/result shows, the pain will be forgotten, it's just like a farmer and the same time, he hunts (hunter), thats suffer a lot to kill bush meat, I was once told that it not something easy for a hunter sometimes to kill ordinary a rat, most time they will trek to a far distance so they could hit their target for that day.
No wonder they normally say, "if the hunter should think of what he passed through before he could kill, he wouldn't give out".
After all the stress and maybe during the hunting, he actually fell or got injured by wild animal.
The causality (cause and the effects) is to get home and give to his family to see them smiling and forget about the pain.
The pain has been forgotten
