उत्तर
After hitting on the wall. Amit’s forehead would have swollen and become hotter. Didi folded a scarf, below on it and kept it on Amit’s forehead because she might have learned this from her elders but it is a wrong practice. Actually, it does not cure the pain, but on blowing, the scarf becomes a little warmer and gives some relief to the pain and swelling.
