I always talk only about my mom in front of my friends.
It is hard for me to actually talk about my dad, especially with those friends who are not so close to me.
My friends (mostly new friends) will ask what my mom work as and I find this very difficult to answer. And I usually answer them she is a business woman.

And when they ask, ‘What about you dad?’, this is even more difficult then the question before. It is very hard for me to answer them.
I find it very awkward if I answer them because they will feel very sorry and the situation will go weird.
How should I answer them?
He is not here anymore? I am afraid some will ask me where he has gone.
He died? The word died is not nice to me.
He pass away? Still sounds very weird.

I will answer them ‘Hah-?’ and usually my close friends will hint to them.
It is not easy to actually tell people thaty my dad is not here anymore.
And sometimes when people ask me what my dad work as, I will just tell him the job he used to work last time and not telling them he has gone.

I don’t bother to explain to every one actually. I don’t think I need to.
