Give someone a rose, how can I reply if there is fragrance in my hand?

If you give someone a rose, you can hold the lingering fragrance in your hand and reply: If you have good thoughts, you will have your own fragrance. It means a very common and trivial thing, even if it is as trivial as giving a rose, the warmth it brings will slowly rise, diffuse and cover in the hearts of flower givers and flower lovers. "There is always a fragrance on the hands of roses, just like perfume sprinkled on others, you can't help but get some." While we pay, we also get a happiness after helping others.
