Answer and Explanation:
Both poems address the idea that all things have an end and that this is inevitable. In “blackberry pickin” we can see that the happiness of harvesting fresh fruits in the summer has an end, as well as the fruits themselves, which do not last forever. As “burning the old year,” it shows that what we accumulate during the year should be reviewed and thrown away if it is no longer useful.
Poems also have differences. While "blackberry pickin" shows the purpose of things as painful, "burning the old year," shows it as a fresh start.
This depends a great deal on the individual person. Also, idealism and truth may well have different levels of significance for a given person.
For me, the only place where idealism really comes into play is in my dealings with my family. I am absolutely idealistic when dealing with my parents demand , What I mean by that is that I try to do what I think is right, not what I think is convenient.
As for truth, I do value telling the truth in all important things. I do not really think that it is important to tell the absolute truth all the time, but I do think you should always tell the truth to important people on important subjects.
