Welcome to what I often think of as "normal life". Where adults can get together - have a great time - without having to be drugged for it!
I'm glad that you got to finally see experience this!
As for the part about saying how you used to feel that ""having fun and laughing" was not cool....." - I remember (and dh and I have even discussed) just how many years I was oh so serious about everything and anything. I think, at the time, I felt that one of us had to be an adult and I was probably holding in alot of anger as well as just trying to deal with everything and keep it together. Dh also commented to me not too long ago how I've always been able to joke around and have fun with other people but not him. In truth, a lot of it was an act through the years to help hide the truth. Nowadays though, I see how much it's true.
We grow and we learn - and you are growing and learning! Enjoy Jessica!
