Answer:

1. You can prevent the cheating student from gaining an unfair advantage over his or her fellow students.If they're caught (and punished), they might realize their mistake. If you never report the cheating, this student might sail through the rest of the term repeating the same mistake.
2. Share what you have. Because maybe someday the children whose begging food to you will become a professional and when they see or recognize you, they will also do what you did to them back then.
3. Do multitasking!. If your brother is still a baby then wait for him till he sleep then do your project but if your brother is 5 or 6 yrs. old, maybe they can help you or tell them that just watch on TV while you doing your project but make sure that your watching him/her because maybe there is something might happen to them.
4. Then just let him/her move out to other group and wait for him/her to regret that he/she switch group OR make peace with him. If you have been friends for too long, you can't just break it in a simple fight.
5. Tell them to stop telling unpleasant about your friend.

That's just what i know!
