Mostly, time of work is the priorty. Anyway, I always look back why people don't pay their time with beloved person. There is many reasons. The first one, they worried that they couldn't return equal love.
This reason is the limited idea of one who love themselves and worried to be hurt.
The second, they worried not to be well loved and discard love from themselves. This reason is a self center idea of one who never given real love to others because they also could not even love themselves.
However, the way to change and love others will make one become loving themselves. Look at the sky and please, practice to love someone you always reject in a life time because love need not someting in return and we will not love for granting, just ...love and to be loved in the freedom mind.
