We were like thieves in the night, sneaking down the stairs to the first level, trying to avoid the creaky step, and then tiptoeing down the basement ...tairs. I opened the door to the dark large room. It was about five minutes to 10. I left Gina, letting go her hand. Whispering, I told her to have a really good time because I wanted to hear all about it later. I left her alone to get used to the light.
