"You are my heart, my universe. You are my heart, my universe."
I knew it from somewhere but did not think about it. Instead I sang her "You Are My Sunshine". She liked it.
Then a few minutes later, I was walking back into the living room and she sang those two lines to me again. Then it hit me! "That's from Big Bang Theory, isn't it??!?"
"Yep."
She sang me a song she heard during the marathon today. She is so amazing.
