I want to write to someone I haven't spoken to in years. I won't violate a person's personal boundaries?
Answer from: Ivan Vorobyov:
Naturally educated in science, in my youth I was addicted to literature...
Look, he's a grown man who suddenly has a brain. If you get too clingy, he'll tell you sometime.
After all, he doesn't like your message, so what? The situation will be worse than it is now? No, you just do not communicate, and you will not communicate, nothing will change. And if he likes it - it will be an interesting conversation.
So try to banish such fears from your mind, there's nothing real behind them.
