As I work my way through corporate life, I keep encountering strange types of people I've never seen before.. It's fascinating lol

I've been seeing all sorts of people for over a decade while moving between different companies,
but it's still fascinating to see new, strange types of people constantly appearing.
Recently, a man and a woman in their mid-40s joined the company.
The woman is very bubbly and energetic,
but the other day, while I was changing my shoes in the shoe rack area, she was standing there holding a small box,
saying, "Ugh, this is heavy. Is there anyone who can help me carry this?"
I usually try to help whenever possible, but I couldn't help but wonder what she was doing with a box that even an early elementary school student could lift.
I just thought she was a crazy woman and ignored her.
The man was a very polite and soft-spoken person.
However, during a recent company dinner, I saw him getting drunk and acting out toward a young restaurant server,
and I completely lost all respect for him.
I've seen colleagues hitting and swearing at each other while drunk quite a few times,
but seeing someone act like that toward a server is a first for me.
As expected, people are the most interesting thing.
I am doing my best to simply stay out of their way.
