Last night a family with 2 sons came into the Fellowship Hall for dinner. The oldest son spotted a friend, ran up to him and grabbed him in a big hug. The younger brother watched the exchange and waited. When his big brother moved away, the younger brother grabbed the friend and hugged, too.
Quite a few people commented on the 2nd hug.
If someone is praised for following your example, you are definitely doing the right thing.
Even if you're only 4 years old, there are people younger than you watching to see how you treat the world.
