My sister is getting ready to sell her 6-bedroom mansion and downsize to a two-bedroom condo. For most people, this would mean spending weeks or even months going through everything, deciding what to donate, what to sell, what to pitch and what to allow in the new place. That’s how it was for me when I moved from our 5-bedroom house to a tiny ranch.

But that won’t happen to my sister. She has plenty of furniture in the home she’s about to sell, but she’ll sell most, if not all of it, without a backwards glance. As for the personal belongings, well, she doesn’t have that many.

You see, my sister is the opposite of a hoarder; she rarely keeps anything. This was predictable way back when we were kids sharing a bedroom. Her twin bed was always neatly made, with just one cute little doll or stuffed animal on the pillow as a decoration. Meanwhile, my bed had at least half-a-dozen dolls on it.

Her side of the dresser held a little ballerina statue and a hair brush. My side was covered with belongings and mementos of all sorts, starting at the imaginary line in the center and running out to the very edge. She often looked at my side of the dresser and said, “You’re such a slob!”

I disagreed; I just loved all my stuff, and I had lots of interests, which automatically translates into lots of stuff.

As a budding writer, I regularly used a toy typewriter I got for Christmas. It was parked on a card table in the corner of our room that I used it as a desk. Like most writers, I was also an avid reader; my Nancy Drew collection took up most of the space on our little bookshelf.

Of course, I had other toys besides the dolls on my bed. I had lots of Barbie dolls so they could talk to each other, and naturally they had lots of clothes, and they needed a furnished Barbie house, which I also had. Then there was my love of sewing, which let me to collect fabric remnants, sewing tools and a collection of patterns.

Meanwhile, my sister had very few belongings because she had very few interests. I don’t remember what she did back then besides fight with me over the sorry state of my side of the room. I do recall that she took ballet lessons, but other than that I think she mostly watched television. To her complaints about my being a slob, I usually retorted that she was boring.

She still is, to be honest. But she’s got the edge on me now, because her move from the mansion to the condo is going to be the smoothest downsizing ever, I just know it.
