Oh, what a piece of work this is... A work filled with regret and love for not being able to see my grandmother before she died!
This piece really stuck with me because I too have regretted the loss of my grandmother, whom I hadn't seen for two years.
It was very good!
One thing that bothered me was how quickly the ending image switched.
The good endings could have been shown for about 2-5 seconds per image! (I later watched the ending scene back on video and was moved to tears...)
