Haha, hey. This reminds me of a phrase in a summary that someone wrote on this site (my memory fails me), but it went something like this- "I pour my heart out because it's the only ink I own"... Or something like that. Anyway, back to the poem- It was very enjoyable to read. The title fits and I like the repetition of it throughout the poem. The dragonfly against the twilight was a bit random, but s'all good. For the general message of the poem, I think the concept can be applied to many other things such as writing or photograph..ing, which are among the many ways of how people express themselves. We just do it because we just do. Haha, and so I agree with your last line, "And even I do not understand its depth." A well-done and awesome poem with interesting ideas. Keep on writing!
