tears

i saw , she really crying.
she didn't want us to see ,
she didn't want us to know ,
she also didn't want us to ask.
Why? why she are crying?
she didn't even cry one time in front of me,
until now , 13 years.
i saw her , her face with tears ,
many drops of tears ,
in the toilet.
she was very different today ,
she didn't even talk with me today ,
until just now ,
when i saw her with tears .
isn't my fault? sorry if it is.
please , stop dropping tears ,
it just will hurt me.
