Goodness and Grateful

At noon, i wanted to take my ordered in my friend's house in Senen. I was so lazy to go by my self, so i asked my maid to accompany me. She is about 60 years old, and she already work with me for 22 years. Her name is Eka. She has a family who lives in her house in Bogor. I was asking her a few questions about her life and how she can survive.
She has 2 daughters, they both are married. The first daughter is so unhappy with her life, her husband doesnt have any job for a few months, lately he got a job as a guard, his salary is not enough to suffice their life and pay motorcycle installment. Therefore, they life in Eka's house. The second daughter are more stable because her husband has a quite good job. Eventhough he has to work from Bogor to Jakarta everyday, they still survive.
Eka still has a mother, she is very old, about 100 years. She is sick and very weak. Her daily activity just sit, sleep, eat, and dazed ; doing nothing.
I was thinking how can Eka suffice her life from her salary to defray her mom, first daughter n husband, also the electricity cost and her mom's meds. Nevertheless, she still thankful .
I was asshamed at myself that sometimes i still complain and querulous about my daily routine and activity when i can easily get money from my parents, and have time for having fun.
Yes, it is our nature as a human being who never satisfy. But God taught us to be grateful in everything because everthing happens for our goodness. God knows what is the best for us. So, be grateful! :)
