Do I care? No I don't. I am not even aware of which way round it is, or which way round I put it. So long as I HAVE toilet roll, I am happy. If anyone got uptight about this, I'd shrug it off. On a range of things I don't care about, with zero being not at all, this is in the minuses.
But that's not true for everyone, oh no. I have seen an elderly married couple have a shouting match over it, that almost came to blows, and ended up with them not speaking for hours. The resentment went on long after, possibly permanently for all I know. I've heard of many families where this really is A Big Issue.
So we could ask why, but first let's look at a dead horse I've been flogging for years, with which you will be very familiar.
The question is not why this one drives me crazy, but why this does and the other doesn't. Why are our peeves selective?
It's a valid question. Even people who appear to nitpick everything, actually have plenty they simply don't care about. While the most laid back, lazy, or apathetic person can be irritated by something.
Well, what do you think? How do we (probably subconsciously) select our peeves?
