How do you express your gratitude?

I express my gratitude with words and deeds.

First, I wholeheartedly thank the person who supported me and provided some service in my favor. Further, I buy some little present, like a book or a cake from a patisserie.

But showing gratitude this way doesn’t mean everything is done and you can continue living as before. I believe we should never forget the people who helped us once in our lives and be prepared to take action when they need our help.
