Very powerful Senryu. Touching and worded effectively..I enjoy such structuring and surprise elements in poems. special Senryu. As for the comma, I definitely disagree with Jamie, it won't work without it, in my opinion.
Superb... A powerful punch in a few words says it all. The beauty of the flower undiminished by the insignificance of the person who gave it. The closure and final filing away of a chapter which will be rarely if ever revisited. This is an excellent example of what well written Senryu's do best - packing a punch whilst still leaving it open for the reader to put their own interpretation on it. Milly xx
