For sure, we all have different ways by which we show gratitude for the things people do for us

We wouldn't be anywhere in the world, if not for the collective effort of other people... No man is an island

For you, it's great that you store every act of kindness in your memory so that you can forever remain grateful to those who show you kindness

Like you said, it's a way of showing one is responsible, and every human should learn to do so

I appreciate that friend of yours who gave his position of work to you 8 years ago, please, tell him, this ☺️
