My grandpa's hobby was photography. Short on space, he had built a makeshift darkroom in an over sized hall closet that was always locked. As a toddler it intrigued me that he would disappear into the hall closet for long periods at a time. No matter how much I begged to be allowed inside, I was always told no and warned to stay away!
One of my earliest memories is the day he finally relented and allowed me to come in with him. I had expected to find lots of toys in there and instead found crowded shelves full of disappointing brown bottles, trays and equipment, but no toys!
It was when the lights went out and the red light went on, that I threw a tantrum! My poor G couldn't turn on the light or let me out fast enough, without ruining his new photos. He hurriedly covered everything as best he could and cracked the door open just enough to push me out. Needless to say I was never invited in there again.
