Welcome and hi!
Yeah, if I had come to books a little later in life, the protective instinct might have been strongest. As it was, they were my security blanket, and no one thought to tell the young child that attachment to books was unhealthy, so that the desire to always have one to hand (and feel uneasy without) was never blunted or modified. Some kids had stuffed animals in their beds, I refused to nap or go to bed at night without at least one book.

Never did outgrow the impulse to cart them around all the time, just let the genres evolve instead. Ah, well.
