You're like a free guy and that's a better state in your family compared to the others. You don't have to be bothered whether you tell them or not because they'd ask you then later on wouldn't care about your answer.
Much better to keep quiet, it's nice to talk things like this with your family but if they ask you to stop talking and that all they want is silence then keep it as they like.
There's no need for you to stress yourself explaining with those jargons and other unfamiliar terms to them. That also saves your time and effort.

At the very beginning, it just got on my nerves. You can't even imagine how much I didn't like it. I had to somehow get out of it so as not to offend my family. I used this practice of answers that just became boring. And it worked. Now no one asks about how I conduct my activities on the Internet. They simply lost interest in this matter. If anyone needs it, then take note. ))
Now I use this method to answer constantly and it all works great. People don't want to hear if a person throws out terms that they don't understand and quickly switches to another topic.
