To me it just means we are getting older. It is nice though to be an uncle. My niece won't know anything right now as she's only like 7 months old. When she gets to 1-2 years old those are the fun years.
I meant that right now my niece is just learning things and realizing what she can do. She also is still trying to remember who is who.
As for getting older, that is just my opinion. I now get called "Uncle Mike".
