What do you think when you see a lady in her 40s

(1)I still feel sad when I see young soldiers in their 40s
(2)And thank you. When I was young, I used to send letters of condolence to military men in kindergarten at school, but I’m still thankful and sad because of my education In a few years, my son will be sent to the army, and I’m already tearing up thinking about it Thank you to all the adults who sent this precious son
(3)On the one hand, I’m thankful that I can talk about my military days with a smile like that. There are many people who couldn’t come back or were injured in my son’s accident, but I don’t think there’s anything natural about our lives Thank you to those who gave up their sons to live in this safe Korea, to those who studied their careers at the golden age of their lives, and to those who served in the military with their loved ones
(4)Watching this variety show and thinking about it makes me realize that I’m old. I’m being silly
