MODALS IN THE PAST FORM

When do we use modals?
* To talk about someone's ability (or inability) to do something
   example:
   "We can find your house without the street plan."
   "She can't have a daughter that old!"
* To talk about an action that is necessary (or impossible, or not necessary)
   example:
   "You must always have your driver's licence when you are driving your car."
   "You needn't carry your passport around with you."
* To talk about a situation that is possible (or impossible)
   example:
   "Do be careful with that glass, the baby might knock it over"
