Spoiled Wife

My sister has a perfect husband.
He always treats her like a princess.
He told my sister that he would do everything for her, he would devote all his earnings for her.
Even when he would strave someday, she could still take his money to buy everything she wants.
Her husband really did everything he promised.
My sister wanted a house, he bought a house for her, even they didn't have enough money.
My sister wanted to get married, they got married and hold a big wedding even they didn't have enough money.
When they complained about my father not lending money for their expense and refuse to provide living expense for my retired father and sick mother, they still went on to buy some luxurious stuff only becacuse my sister wanted them.
Today, it's her birthday.
She called me this morning and asked me to go home immediately to celebrate birthday for her.
It means I have to send her a big gift and treat her a big feast.
It's so unbelievable cause I am in Taipei and she is in Taichung.
It takes more than two hours for me to get there.
She even ask me to take the expensive High Speed Rail to cut time.
I refused directly.
And she continued to consider about come to Taipei to have my treat and big gift, I said feast is ok but gift is too much.
She felt unsatisfied and said I am so negligent of her birthday.
I were annoyed.
Whenever my birthday comes, my family celebrate for me only when I'm home, and there is only a cake.
I feel it's ok and never ask more.
However, how could my sister dare demand so much?
It's so greedy！
I'm not rich and had no job for three months in this year for the exam.
Most of my saving is stuck in funds.
I almost have no money now.
She knows all about this and still wants so much from me.
What's wrong with her?

And then, she is pregnant now.
Cause they have no money, she always reminds me to prepare gift for her baby.
Oh,....it's your baby, not mine.
Send her gift is ok, but don't expect me to feed her...

Such a spoiled wife, and such a burden couple....
