Suppose, you are Sarjis. Your friend Hasnat doesn't know when and how to wear a mask. Now, write a letter to your friend telling him the right method of wearing a mask. (মনে করো, তুমি সারজিস। তোমার বন্ধু হাসনাত জানে না কখন ও কীভাবে মাস্ক পরতে হয়। এখন, সঠিক পদ্ধতিতে মাস্ক পরা সম্বন্দ্বে জানিয়ে তোমার বন্ধুকে একটি চিঠি লেখো।)

Dear Hasnat,
Hope you're fine. I'm fine too. I've just received your letter in which you wanted to know when and how to wear a mask. I'm now writing about this.
You know the best way to prevent respiratory diseases is to follow the rules of hygiene strictly. For this, you have to wear a mask while going out or meeting someone. You have to wash your hands before putting on your mask. You should put the mask over your nose and mouth and then secure it under your chin. Make sure you can breathe easily. Don't touch or adjust your mask frequently without cleaning your hands. If possible, don't use a mask twice. No more today. I hope you'll find the instructions useful and follow them accordingly.
Yours ever,
Sarjis
