Are we under one roof

What kind of sister is this?

I face a lot of friends who use to be like this,

But why I'll face the same at home?

After she come back from home.

I feel that nothing is secure anymore,

I get a lot of negative feedback,

I get a lot of betray,

Today say yes, tomorrow say no,

It seem like my sister can't be relay.

She expect us to rely on her,

Once I relay on her,

She run away,

I feel so helpless, and weak.

I can't say anything,

I trying myself very hard not to think,

Love everyone even the people we hate,

It give a lot of challenge.

Today, I confront with her,

It voice out our problem,

Mum and dad just let us be,

End up they try very hard to comfort me,

I feel much better,

This shown that age is not a problem.

I know after confrontation,

There is a hard feeling toward each other,

I must be tough and persistent.

Hope tomorrow will be better.
