Sentimental Box (Fiction)

It wasn't till years later that Becka realized she would keep her job at the law firm. She had plans to go away to school, but that was 15 years ago, and she had already started a different life. It didn't sadden her though.
Sure, she had faced a few rough years with her dad dieing, and almost leaving her husband, but her grief had passed and her marriage has been strengthened.
This was her daughter's sixth Fourth of July celebration, her son's ninth, and they were spending it this year at her sister's place. Since her husband's job location has been switched every couple of years, holidays were usually held in different locations. After setting up the picnic table she began to retrieve the decorations. Judy, her sister, was gabbing away about the recent news as both of their children ran through the yard. The wind was blowing a calm gust and laughter surrounded the children.
Becka watched silently, leading Judy under the impression that she was absorbing every word said. She interrupted her, "You know Judy, I just realized, our kids. They don't have the same childhood that we had." The way that the kids were playing under the Maple trees made her see they were making an attachment to the place they were at. For her children this place would become a memory in the sentimental box in their heads, and as they'd grow older, now would be their childhood. This is how they would spend it, and it would never be the same as her experience. 'When did I become my mother,' she thought to herself. She now knew why adults would cry at the strangest moments.
