Animal Lessons Part 1

This reminds me of someone I know. She was constantly thinking that she was better, stronger, faster and cleverer than the person next to her.

Very optimistic too. Both of what she was able to do, and even of the people about her.

A really nice person who had somewhat idealistic opinion of herself and people around her.
Now what sort of personality is this? A "D"? Or an "I"? Or perhaps a "C" or an "S"?

Comments welcome!
