Dear Principle, I am writing to ask your help and understanding. There are things happening so quick in my life. It makes me think about my career deeply. My mum suffered the eye disease and it caused one of her eyes almost blind. After this occasion, she has to go to hospitals quite often. Definitely, she needs my accompany. To be a responsible teacher or a sweet daughter , it is not an easy decision for me. Based on the time limit , this semester is going to the end. Winter vacation is coming soon . I realize I don't have time to hesitate. Here I have to submit my request that I am not able to teach in Mincqucan elementary school .This timing seems a better moment to make or accept any change. I ask your understanding. I apology any inconvenience caused by my side. Best regards,
