Hope you are doing great. I’m writing this letter to explain you about the annoying noise from my home and of course, I want to apologize for that. The sound which you have been listening was of my nephew, who is autistic. Autism is a medical condition, which makes people behave abnormally. When they get high, they will create noise and will throw the objects. His mother had to go to an urgent meeting, that’s why she left him with us for a day.
