Answer:
. The boy comprehends that, despite his best efforts, he cannot escape time, and he too will become a part of history.
Explanation:
The boy dislikes the idea that the whole family has been keeping their mementos in the chest. He does not want to feel engaged into looking into the contents. "f...contents of the chest never came quite clear,.....because he didn't want to know."; "....but he hadn't wanted to listen. A thing so old disgusted him...", these words reflect the boy's feelings towards the passage of time , but these seem to be senseless when <em>he</em> gets <em>shocked </em>on coming across <em>his own</em> drawings. He drew them when he was five.
