Hi Jaagrit,
It's like this:
On the same day (1 December), you posted two questions. One of them was answered immediately, but you couldn't be bothered to acknowledge that response - to say or indicate whether it was helpful and/or enabled you to fix your problem, or if it needed further explanation or didn't help at all.
You don't need to acknowledge - it's entirely your choice. But you must not then expect an endless stream of help in only one direction.
Regards,
Dave
