1, 'Attitute' has nothing to do with word 'bright'.

2, Word 'sun / sune' is repeated from different points of view in first & second line. Lost significance & focus.

3,in fourth line , you wish: pain should even cross.. extreme limits until someone realizes a small joy ..

4,in sixth line : 'loss' is never a prerequisite to appreciate ones' possessions...

5, Total six lines ,,,seldom liked , better five or seven..for sharpness of ideas..
