Let us be grateful to people who make us happy, they are the charming gardeners who make our souls blossom.
the original quote in French: “Soyons reconnaissants aux personnes qui nous donnent du bonheur ; elles sont les charmants jardiniers par qui nos âmes sont fleuries.”
Gratitude, towards people who makes us happy, those persons as per Proust, are like gardeners. Gardeners who plant seeds and take care of their full growth process. It feels good to "cultivate" happiness isn't it?
