Dear Student.
Here are a few points that will help you in framing your answer:

• ​​​​​​They give us the feeling of nostalgia.
• Remembering the good times can reduce stress or depression in people.
• It makes us happy for the things we have accomplished so far.
• Remembering old memories can be very comforting, like the narrator in the poem who feels very cozy in his room. 

We hope that this answer solves your query.
