long lost sister

I have a sister that looks like me,
I have a sister that is just like me,we laugh and sing and play all day,
till I make a big mistake,
I cry at night and some during the day I say sorry,
I beg for mercy,
Trying to get sympathy to show her I can change,
I am grown I am strong, I am your sister that will carry on,
Please hold me tight for I cant do this alone,
for when I have a week moment,
Its a family member like you that keeps me strong.

Thank you to my family Vicky M. and Teressa H.
