You always tell me everyday that happiness left your life the day I was born. You told me dad left because of me. So today, I want to change things. I want you to be very happy and live as if I never existed. You told me you’d never look at me with love, but I always loved you and i admired you as the best mom on earth. I hope one day you will think of me, I hope in heaven you will finally hold me and kiss me. The best gift I could give you is leaving your life as you’ve always told me you wishedl was never born. I love you mom. Happy birthday.” Please be careful of what you say to your children, you might not know how they are able to take them. Words do cut deep.
