I have often experienced this phenomenom myself. When a cub's boundaries are not taught to him as he grows up, he does not learn respect for boundaries, his own or those of other people. He doesnt respect them because he doesnt even SEE them. He cant read the signs!

This becomes tiresome to the other bears and they ignore him. The bear feels bad being ignored and tries tries again. What else can you do but try to learn from your mistakes.

But also, figure out where your own boundaries are and Smokey T. the heck out of those!
