Immature?

I was lamenting to a friend about how immature I was. When she asked what I meant, I told her about my immature reaction to a criticism lobbied against a group I was a part of. She so wonderfully pointed out that a person can react immaturely but not be an immature person. And because I have become so wonderfully teachable and because I love life/light/truth and because I especially love life/light/truth that makes me look good, I immediately abandoned the woe-is-me-I'm-so-immature-way of thinking.

She is right - one can have an immature reaction and that not mean she is immature.
Thank you God - thank you friends.
