I feel like middle aged or older adults have such a good sense of themselves, at least from an outside perspective. Everyone I know from family to co-worker to teacher who is within this age range is so easy to describe. Their characteristics are easy to point out and their personality is very clear. I feel like this isn't as true for young adults and teens and especially not for kids. Maybe it's because we're open to changing ourselves more and definition hinders our ability to grow. I feel like this is obvious but an observation non the less.
