"What you allow, you encourage." ~Michael Josephson
Whether you're raising children, educating children, or trying to make a positive difference in yourself or your workplace, you want to set an example. When we turn a blind eye to the little things that are on the verge of right/wrong, we allow that behavior to keep happening. "Oh, they're just a kid...and kids will be kids..", "Oh that's just that person's personality, they didn't really mean it...," "Oh, they're just having a bad day...". And "Boys will be boys?" No way! Not if parents teach their boys to become men! And girls can be ladies and it's not a bad thing! God made each gender to be unique, special, and able to do things and feel things and accomplish things that the other gender wasn't made by Him to do. We were each uniquely made by God for a purpose - His purpose.
When we allow things that are wrong, we become part of the problem and not the solution.
Take time to lovingly correct your children, your students...stand up for yourself (in kindness) when someone offends you. But be KIND. Be LOVING. Be understanding, but teach and instruct and don't neglect to do so.
If no one tells them something is wrong, how will they ever know?
Train up a child in the way he should go, Even when he is old he will not depart from it.
