First of all thanks to everyone for answering and sorry for replying belatedly - it slipped my mind that I had asked a question here!!
Now about the sentence I asked, well sorry again for not being clear. I wanted to ask the usage of preposition "of" in it - and of course the whole sentence is making sense or not. I forgot to include the question about preposition part in my first sentence. Like the usage of "discussion of". Anyway if something is wrong or missing it will get pointed out!!
As for whose sentence was it? Well, it was mine and I used it in a family Whatsapp group. Realised later the grammar in it may not be right - it was sounding OK type to me. So I thought of asking about it in this forum.
Thank you all for the replies. So the sentence and its syntax is wrong or the grammar itself is wrong?
