because of that sad feeling but don't want to be asked by others 'what's wrong' or to even explain anything

When you want to fly back home as fast as you can but cannot do so because you are so so far away from home. When you want to cry from time to time because of that sad feeling but don't want to be asked by others 'what's wrong' or to even explain anything. No matter how hard you try to hide all the pain and sadness to yourself, you can't just help but blink your eyes a number of times while looking at the ceiling. Thank you for this beautiful reminder - you might be preocuppied with so many things, work, school, etc, but never to forget to mourn properly.
