A long long time ago, there once was a family of bears! 
 One morning, when the sun came up, mama bear and baby bear went up to papa bear as he was still sleeping. 
 `` Papa bear!'' baby bear shouted, `` it's time to get up! Come play with me!'' 
 But papa bear was still very tired 
 `` No...'' papa bear grumbled, `` Let me sleep some more...'' 
 And closed his eyes yet again! 
 `` But papa bear!'' baby bear said, `` You promised to play with me!'' 
 `` But it's so comfortable in my soft bear-bed!'' papa bear said! 
 `` Come'on!'' said mama bear, `` go play with your son!'' 
 And so after applying a lot of verbal force, papa bear got up to play with his son! 
 
 Then evening came... 
 And it was time for bed for baby bear! That's right, baby bear has to go to bed as well!: - ) 
 `` Looks like to sun is setting!'' Sighed mama bear. `` You know what that means, little one!'' 
 `` But I do n't want to go to bed! I want to keep playing with papa bear!'' baby bear objected 
 `` If you do n't go to bed now, you'll be too tired to play more tomorrow!'' papa bear argued. 
 `` But I have n't scared any hikers yet today!'' baby bear continued. 
 `` You can scare some hikers tomorrow with me, I promise.'' Said papa bear. 
 And so, baby bear went off to bed after having had a lot of ( verbal ) force applied to him. 
 
 And that is also how the Newton's first law of motion works! 
 Objects in rest want to stay at rest, just like papa bear wants to keep sleeping in the morning. 
 And Objects in motion want to stay in motion, just like baby bear wants to keep playing when bedtime is near! 
 And now, bedtime is here! Goodnight little children!
