Would and Used to for the past

We use would and used to to talk about habits in the past. However there are a few differences!

 * Habits in the past

Examples:

When I was a child I would sometimes go to the park.

 Used to 

We use used to to talk about:


 * Habits are finished, and now we don't do.
 * State or situaton in the past.

Examples:

''P.S. Be careful with the negative and interrogative forms of used to! Why?''
