***** NOT A TEACHER *****
Good morning, Mukul.
(1) Are you referring to the idiom "to be called on the carpet"?
(a) This means that the boss (or any superior) calls you to his/her office
because s/he is very angry with you for something that you did.
(b) I do NOT know how this idiom started.
(i) But I remember it this way:
The boss's office probably has a nice, thick carpet.
Have a nice day!
