Once when my sister and I were big-enough little girls to take a bath partly unattended, I had the idea of adding perfume to the water to make it smell good. (This was before stores like Bath & Body Works existed.) Ever the big sister, I was the one to lift from the warm water and dash naked and dripping across the bathroom linoleum to the counter where my mom's things were displayed.
We didn't add just one bottle, of course. We added perfume from ALL the bottles! My mom was not too happy when she discovered us! What smelled divine to us didn't rest so well on my mother's olfactory senses... and there was the waste, of course. A drop might have been fine, but we'd used far more than a drop!
What's extra interesting to me is that there were any perfume bottles at all, as my memories/ideas about my mom do not include such frivolities. She's always experienced sinus issues and is particularly sensitive to smells. But apparently, at one point in time, at least, my mother had not just one bottle of perfume, but several.
