To acknowledge/ not acknowledge , or say thanks for a gift received

Re: To acknowledge/ not acknowledge , or say thanks for a gift received

I thank others frequently too :alhamd: and I don’t have any Caucasians in my family. And I really mean it when I am expressing gratitude, not just for the sake of saying so.
My religion teaches me to thank others.
I was quite young when my mamu(who is 15+ years elder to me) had said JazakAllahKhair to me for something trivial and I was like mamu isme JazakAllah k kya baat hai and he told me that we are supposed to thank for everything anyone does for you.

I have even had people thank me for doing what was actually my job. And I barely come across Caucasians.
