Kigo sir I really enjoyed reading your post because you have beautifully presented the points mentioned in your post,

It is very good to know that if you are participating in the service and you have chosen to protect and security in all areas, it is a very good responsibility, I wish you all the best.

I'm just so sad that you lost your sister, so sad that the sister had a child who was too young to hurt her mother, I wish you good luck in this competition.
