Why?

Is it a natural male/female divide? Or a mother/anyone else one? Or maybe it's just me.

I'm untidy. By inclination and by choice, I live in more-or-less chaos. I'd find it quite unsettling to have everything in exactly its proper place, every cushion plumped and each surface clear.

On the other hand, I have a inbuilt clutterometer that starts to sound an alarm when a certain degree of overload is reached. For example, let's say that a member if the family is doing some paperwork. I think that it's entirely reasonable to leave it out to finish the next day, even if it spreads all over the table and seeps onto the floor. A half-done jigsaw or Lego edifice was treated with similar tolerance when my children were younger. However, if it's still there weeks later, untouched, gathering dust, it's going to get cleared away - by its owner if he's there or by me if it's in my way. Naturally, if I do the clearing, however festooned it had become with grimy cobwebs, that would be the day it would be required and lamentations would assuredly follow.

Whatever housework is done around here is normally done by me. When my children lived at home they and the Sage helped, but nowadays if I don't do it it isn't likely to get done at all. The exception is the dishwasher, which is filled or emptied by whoever is around, and recently, as I've been busy, the Sage has emptied it most often.

Today, I fetched a glass and cut open a couple of oranges. "Would you like some orange juice?" I asked Ro. He said yes please, so I squeezed the juice, poured it into the glass and gave it to him. The Sage didn't want any juice, but he was by the cupboard. "Would you get me another glass, please?" He took out a pint tumbler. "Sorry, there aren't any smaller glasses."

Now, I'm not a fussy person, but that was all wrong. I couldn't put the juice of two oranges into a pint pot. I couldn't (at an appropriate time of day) have drunk wine out of it, either. I went to the cupboard, reached (no need to move them) behind the pint glasses and took out a wine glass.

To return to my question at the start. Is it a male thing or what? First, why could he not see that there were smaller glasses behind the big one? Second, and I have explained this now, when I put glasses away, I automatically group them. A front-to-back row of similar type. I am emphatically untidy, disorganised, casual, but this seems normal to me.

The Sage was impressed by my reasoning and has assured me he will follow my example in future. But I've always done it and quietly tidied up after him, for to mention it except when the moment presents itself as it did today, would be the action of a bore and a nag. And in nearly 34 years, he had never noticed.
