Frustrated by my carelessness

My dear Lower Back,

I'm sorry, I hurt you in the rehearsal today. I hope you are well. I know you are mad on me for my careless, I can feel it, you are not willing to let me move you anymore. I know you need to be stretch and warm up before I make you move. It was all my fault, I promise I will take a good care of you in the future, so, please forgive me. I still have so many thing want to do, I can't make it without you!

Hope can dance with you again in the near future!

Sincerely,
Jo ;P
