What a lovely day you spend with your daughters!!
Exactly!! house feels empty when you don't have your love ones around you .While reading your post I remember the time when my sisters went to do internship to another city. I saw the change in my mothers behavior, She used to call my sisters all the time. Even sometimes she used to wake up from her sleep and ask me to call them for her.
Things can be really challenging at such times. But we have to be patient .I am very glad that you are sacrificing for there education.
Seeing your children's happy is the biggest happiness in the world. And the fact that some one is happy because of you makes you happy.
That is what our religion teaches us.
have a great weekend. May Allah Subhan Allah bless you.
