blocks are the worst, specifically [completely silent blocks](https://www.youtube.com/watch?v=PQGYv6Khk8E&t=38s). I used to think it's the repetitions that I should avoid, but it turns out it's the blocks that do the most damage. When you have to say sentence one, sentence two, sentence three, but you get blocked in the middle of the second sentence, and they conclude you're done and respond to the wrong message. Sometimes the wrong message is so offensive.
