It's frustrating when someone copies me. That's normal. Kids get upset at it at an early age - "Hey he's copying me!" Unfortunately I must admit that I am responsible for copying others at times or "following on their coattails." Sometimes it's just cause they had such a good idea. I would like to think that I still give them credit for what they think up first. In the end though we can try to remember when we ourselves are victims of copying that "imitation is the highest form of flattery." Right?
