The wife and I went to my 30th a few years back, when we first got there I wasn't sure we were at the correct address so we sat in the parking lot for about 5 minutes to see if we found the right place.
I told my wife " I think we're at the wrong place honey there's just a bunch of old people going in the building" when all of the sudden I realized that I knew those old folks.
That's when reality set in.
Dang I'm old.
