Feeling a Bit Like my Dad

I am the third of four children in my family.
I have an older brother and sister, and a younger brother. And although we don't see each other nearly enough these days (Living in three different states will do that to ya!) when we do get together we have such a good time. We laugh and reminisce and tell stories and hug ad infintium.
It is so much fun!
I honestly cannot count the times I have heard my dad say, "It is so good to hear you kids laughing together. I love that sound!"
And, truth be told, even as an adult I cannot count the times I have heard my dad make that statement and in my mind I have thought, OK, Dad. Whatever. Not really understanding why he thought it was so wonderful that his kids were having a good time together.
But...
But then, a couple of days ago I was sitting at the table eating lunch with Brian - while Matthew and Elizabeth were in the kitchen making their own lunches. I don't know what was the cause of the commotion which was happening, but the two of them were laughing and carrying on and having a good ol' time. And I found myself pausing in my conversation with Brian to just listen to their laughter, their banter, their joy.
It brought such delight to my heart to witness two of my children simply enjoying life with one another.
I thought, It is so sweet to hear them laughing together. I love that sound!!! Which was followed immediately by the thought, Oh, wow. Now I know what my dad has been meaning all these years.
Then I vocalized my thoughts to Brian, and we smiled at each other - knowing this realization was one more confirmation that we're getting old, and we're continuing to become more like our parents.
And then?
I called my dad to share the experience with him.
