Well I just wanted to share this important lesson that I got from the movie, so it won't be like the other reviews as I won't be nitpicking the details and placing some scores. [spoilers ahead btw]

Say what you want while you can. For me, this was the main thing that the Violet Evergarden movie wanted to tell us. Although it may sound a bit cliche and generic for some, I believe this is still a necessary lesson that more people need to realize. Kyoto Animation creatively presents the said lesson with 3 such situations.

1) Daisy (grand-daughter of Ann, the girl who received 50 letters every year from her deceased mother):
As the movie starts, Daisy is shown to be quite troubled with the passing of her grandmother. She is seemingly upset that her mother was not able to spend a lot of time with her grandmother (Ann) before she died and blamed her for often choosing work over family. However, she murmurs to herself that she knows that her parents are only doing this to support the family and that they truly love her and her grandmother. Having read and learned the story behind the letters her grandmother received, she then gets inspired to write her own letter as well which she addressed to her parents. In this, she thanks them and states that they love them which reassures her worried parents. In this situation, she was able to say what she wanted while she could, and will surely continue to do so for the rest of her life after learning its importance.

2) Yuris. It would not be an exaggeration to say that this was the heaviest scene in the movie and understandably so. As we know, Yuris has been sick for a long time and was beginning to feel that his time on Earth was almost up. However, he still could not express his real feelings to his family every time they visited. He then resorted to placing his feelings in a letter which will be given only after his death since he has decided that he will never have the courage to be able to tell them in person with the little time he had left. Unfortunately, he did not have the opportunity to create the last letter with Violet which was to be given to Lucas, but thanks to the growing telephone technology, he was able to express his real feelings in his final moments. In this situation, he was not able to say everything that he wanted to say, especially to his family.

3) Violet and Gilbert. Apart from Gilbert's supposed dying breath of "I love you", they were never able to tell each other what they truly felt. For Gilbert, it is seen that he is overcome with guilt by using Violet as a war weapon when instead, all he wanted was for her to live a normal life just like any other kid. Sadly, he did not have much choice since he promised his father to take over the military in place of his older brother, Dietfried. With this, he felt that he had robbed Violet of a normal life and turned her into a murderer instead. For that reason, he could not bring himself to show his face to her again and would rather live a normal life of his own which he had also long yearned for. Aside from the already heavy guilt of Violet, he also wanted to attempt to make up for the Escarte island families left behind by the soldiers that his army killed. As for Violet, she was only able to understand regular feelings and emotions after Major Gilbert "died". For this reason, she was not able to tell him how she felt while they were still together. Although she made her a soldier, she was still extremely grateful to him for accepting her and treating her like a human instead of leaving her to die. She was glad to have someone always look out for her. She was happy to have someone to stick beside to during extremely troubling times. In this situation, both of them were not able to express all of their feelings due to the supposed death of Gilbert. However, life gave them a second chance and they made the most out of it. Though in reality, second chances hardly every come by, so when they do, we should definitely grab the opportunity.

If you've made it this far, thanks for reading!
