I received Pepero at work, and I realize how much I've changed.

When I was younger and in a junior position, I used to give out Pepero to my seniors, but at some point, I stopped doing that,
and I hadn't even thought about giving any to my employees.
Today, after coming back from field work, a female colleague from another department quietly came by and gave me some beautifully wrapped Pepero.
I hadn't prepared anything and wasn't even thinking about giving any out...
I said thank you and that I'd enjoy them, but I feel somewhat apologetic... haha
