On many occasions, if the respond is ‘No’, it seems to be odd or unpleasant. Suppose if a person responds ‘No’. When we ask him for a tea or coffee or anything. This response ‘No’ is not a good expression. Atleast he should add some words to ‘No’ like ‘Not thanks’.
If some one says ‘No’ we should react saying. “It’s all right”, “Oh! It’s OK”, ‘Thanks for it.”
