Assertive ; boldly positive or confident,persistent. Aggressive; boldly hostile, quarrelsome.  Looks like these have two different meanings, so I think I prefer the positive over the negative.

 My daughter has a passive nature and she has locah. She has always had a sweet disposition, (except for when they had her on too much Cortef) My son, noncah is the opposite of her, he is more assertive but still has a great personality.

 I believe that kids and people will go as far as you let them. I will not allow negative aggressive behavior in my house. I teach my kids to have respect for one another. There is nothing wrong with obtaining what we want, or achieving our goals. I just wanted to acknowledge the difference between the two words. One is having confidence the other is simply being a bully, and I don’t tip toe very well. :o)
