Well the true story behind this was that I was planning to have some special friend for the woman at the end. An animal was what I had in mind. But the common dogs and cats have been used in the first and second scene. So the next common pets would might be birds and/or fish. I was trying to go for a more magical feeling for the last scene, but after redrawing it over and over again, I gave up, and just added a Twitter bird. And gave the story another meaning besides just "special friend". So in a way, that Twitter bird was added on purpose.
