I was about 10 when I started to get into theatre. My grandparents took me and my cousin to go see Mamma Mia! on Broadway. I liked it so much that I got the soundtrack. In the actual song titled "Mamma Mia!", Donna sings, "I can't count all the times I've cried over you." Up until a couple weeks ago, I though she was saying "I camped out all the times I cried over you." I pictured a scenario in which she couldn't even sleep in the same house with the guy.
