“Thank You”…”No Problem”

Responding to "Thank You",
Once was 
    "You're welcome",
Which now has morphed into,
    "Forget it",
    "No worries",   
    "No problem",
    "You got it".
Or, wordlessly nodding 
In "Thank You's" direction.
But fewer the times you'll hear
Old-time responses,
    "The pleasure is mine",
    "Happy to do it",
    "Glad to help."
And even more seldom...
    "You're welcome".
