My dear, sweet Sephiroth. I didn't for the same reason I didn't back in Havenwell. Because I wanted to learn something new and potentially surprise you with it!

The truth is she could have asked Sephiroth to teach her, knew he would have been gentle with her, but at the same time she'd really wanted to try and do something 'herself' so that she could eventually show him and impress him with her new abilities! Or utterly embarrass herself at how bad she was. That was also an option.]
