and I was that stranger.
I have a lot of DIY home improvement experience. I've owned (and lived in) 5 houses along the way, varying from brand new, contractor grade everything, to a house built in the 1920's that needed a lot of upgrades. Our latest house was also brand new when we bought it, and I am now getting around to painting and making some cosmetic changes.
So, I was in the lighting aisle, selecting a new fixture for above my kitchen sink. Behind me was a family (I assume) of mother, father and 19-20 year old daughter. They were looking at the type of fixtures that go over a bathroom sink. This was obviously to be the daughter's choice, and she was saying she didn't like any of them because they were all hanging down (by this, she meant that the globes over the lightbulbs all had the openings at the bottom). She didn't like the ones without globes because they were "just ugly".
Upon hearing her, I turned around and said that "Almost all of those fixtures can be turned around so that the globes are facing up." The young lady's eyes lit up and they thanked me for that information. I went on to say, "Personal experience has taught me that you don't want the globes facing up, because all the dirt and dust just collects in them and you have to take them apart to clean them." The father told me, "That's a good point. I never thought of that." The mother asked what I meant by taking them apart. I said, "You have to take the bulb out, to get down to the bottom and take the globe out to give it a good cleaning."
As I already had my purchase in hand, I left at that point. I know it was impolite of me to let them know I was listening and by interjecting my unsolicited opinion. How far into E-hell have I descended?
