Hope it goes well

Haiz...
Heart broken for me looking at a couple quarrel...
What is love..??
What makes love long-lasting..??
Ever seen my sis and her b/f quarrel...it makes me sad...
Cause i never seen my sis so happy ever seen this guy came to her life..
When i knew they were quarreling,it made me sad...
To remain a long-lasting relationship,them both have to give and take...
To remain a long-lasting relationship,them both have to know how to sacrifice...
If them both can't do so,there's more to come in future if marriage is occur...

I hope in my bottom of my heart,they will be together...
I hope in my bottom of my heart,my sister will be happy...
Hope everything goes well between them...
