Give constructive arguments

You can give criticism by helping someone with her problems

If the person is having a hard time, help her

If the person is with problems, try to help her

If your friend is suffering from bullying, ask him how and help him

If you notice someone is being excluded, try to talk with your teachers to have an assembly about bullying

When someone is helping you.

WHEN SOMEONE HELPS YOU WITH YOURS DIFFICULTIES

What goes around, comes around

You can understand people feeling

Be in the other place
