The fact is saying ‘thank you’ has something truly magical about it. Like sorry, it’s just words, but they act as shorthand for so much more.

Thank you shows our appreciation and conveys our gratitude. But more than that, it is a sign of respect to the person who has helped you (or given you something).

It is an indication you do not take them for granted, and an acknowledgment that they matter. And that is why saying thank you matters.
