Yes I agree with receiving Thank You notes.
It seems in my experience that it's hit or miss.
Maybe even generational
I generally never received a thank you but out of the blue someone
will surprise me and say thank you.
We live in a society of narcissistic behavior. My own daughter married a year ago
I never received a hand note just to say thanks Mom for helping not have I received
a photo of the pictures I was asked to stand pose for
It's a society that sticks it's head to the side only looking one way and saying
or issuing gratitude it's part of the process.
