Blocks are worst. When they assume you're finished and react to your unfinished sentence, and you realize the unfinished sentence is the exact opposite of what you meant to say... I'll give you three examples. Imagine if the block happens right before the bold part. * your birth day? I don't know **if you forgot. It's tomorrow.** * you are like my mother. **she is wise**. * I am a proud supporter of the A**NC**.
