happy birthday wiahes for sister in law

A sister is someone special to me.
A sister is someone to fight with.
A sister is someone to cry with.
A sister can sometimes understand you better than anyone else can.
A sister is there for you through good times and bad.
Some sisters are close.
Some are far apart.
Sometimes you might wish you could change your sister.
But if I changed just one thing about my sister it might ruin something.
Of course my sister wouldn't be the same.
But most important it might ruin our sister relationship.
We are as close as we could possibly be.
Some people think a sister is just a sister.
But my sister is more than that.
She is and will always be my best friend.
And my sister will always be very special to me.
Because I couldn't picture what my life would be like without her.
