My smallest juvenile is like that too! I walk in the room and immediately he demands attention, and I can tell its attention because he cares less about food until I pay attention to him, even strawberries. Of course he likes me even more when I put food in there. If you really want to see personality, get sulcatas. My big one weighs about 63 pounds and he's really like a big dog. He demands attention as soon as I go into the backyard.
