sentimental and big
Moving affords one lots of opportunities to decide whether to keep or get rid of a lot of stuff. The easiest is probably just stuff: will I use this and is its size/ weight something I’d be will to pay the expense of keeping.
Sentimental and small is easy too: yeah, I’ll keep that small stack of papers from that summer job in Germany.
Sentimental and big: that’s hard. Last night I threw out a section of a grad school project that I was pretty proud of. But it was big and weighed a ton. Goodbye pneumatic-powered nerf gun with linear and rotational control.
