The content seems focused on the use of "used to" and "would" for describing past habits and situations that no longer exist. Here’s a brief summary of the key points:

### Key Points on "Used to" and "Would":

1. **Usage**:
- "Used to" and "would" describe past habits or situations that have changed.
- Example: "I used to live in London" or "When I was a child, I would play outside every day."

2. **Restrictions**:
- "Would" should not be used with state verbs (e.g., love, have).
- We don't use "used to" or "would" to specify duration; the past simple is used instead.
- Example: "She worked in a bank for six years."

3. **Negative Forms**:
- Phrases like "never used to" and "would never" are common.
- Example: "I never used to save money."
