A pat on the back, an arm over shoulder, or a hug can often be the only way that love can be expressed. Use them all. Talk back to TV, read editorials aloud and offer caring alternatives to the hateful expressions. We cannot allow the negative people to win just because they are louder. The big tragedy in all of the negative stuff on the TV is that it is the only voice in the room.
Nobody is worthless, everybody can serve as a bad example to someone.
Sound off about what you believe and why you believe it to your kids. Your actions will define these and many more words. Continually look for opportunities to model love for your children. When you are at the point of sending your children out to live in the street, that is probably the time when their heart is most open to receive your message. Be the adult in the situation and express your love at that time.
