I vented a little to SN's friend, I need advice.

Yesterday, Thursday, I opened my laptop, and on my laptop I opened the SN website, suddenly my office friend saw me when I opened the SN website, and he asked me, "what are you doing?", then I answered, I was discussing with friends I'm on SN, many of my friends tell me about stories, technology, books, bitcoin and much more.

Then my office friend asked again, what are the benefits of joining SN? then I answered, I joined SN, I got a lot of experience from friends at SN, I was very happy to see input and suggestions from friends at SN. and I also piled up some Sats there, then my friend asked me again, it's no use for you, you should just work in this office, if it doesn't produce results for you, don't join, then I object to my friend's statement in that office, I was silent just, and don't continue my comment.

What action do you think I should take against my coworker?
