I don't know that this has much to do with being gifted (presumably) but it does explain much about our difficulties with trying to get DD to do anything she doesn't want to do or any attempt to discipline. DD6 is quite stubborn, usually very sweet but prone to some mind blowing tantrums and power struggles.

DD6 and DD2 were eating lunch. DD6 was bossing little sis and telling her exactly how she needed to eat and how many bites she needed etc. I reminded DD6 that she should just eat her own lunch and that she was not the boss. She sighed heavily and said, "Its just that I am the boss in my head and its hard to keep it to myself."

Exactly what I thought she thought but funny to hear her say it!
