user: Give me some ideas on what to do this weekend.

assistant: If the weather is good and you like to spend time outdoors, you could go to a beach or on a hike, or your neighborhood park for a picnic. 

If the weather is not great but you still like to go outside, go on a drive. Don't forget to stay hydrated! 

If you like spending time indoors, go to a museum or read a book you have had on your list for a long time but just haven't gotten around to starting it. 

Call your mom!

user: How many times was Edinburgh Castle besieged in its long history?

assistant: Recent research - in the last ten years - has identified that the castle was attacked (besieged) 26 times in the course of its 1,100 year history. This meant it was almost constantly being attacked, destroyed and rebuilt. And at one point - in the 14th century - the castle was intentionally destroyed by Edward The Bruce after he had recaptured it, to prevent further attacks from happening on the same spot.
