One of the three saturdays this autumn when the siporeks we ordered would arrive. I did say that they should call a day in advance, as I'd need to raise a moba to unload the stuff, but they did it by having the truck driver stop somewhere nearby, call me on the phone between 6 and 7 in the morning, and say that he wants this unloaded by noon. Each time.
It was a nightmare, I called pretty much anyone I could remember - people from the MPSŠC, friends, whoever I could raise so early in the morning. I don't even remember who I got - several guys from the school for sure (and I did get a return call from two, which I duly returned), Eči, Veca's husband, Sneca's too, perhaps Loba (maybe not this time, but he did come a couple of times).
We already had three wallnuts growing in the back, where the yard will be. I took care to line the unloaded blocks around one of them, as it was slightly to the south of the middle, to provide shade in the future. However, it didn't survive, as a couple of months later the masons, who built the house for the neighbor just behind us, chopped it for fire and used this niche to build a little fire to make coffee. But the other walnut, which was covered by the same plastic foil which I left over the unused cement sacks, survived. That one is smack in the middle of the yard.
I suppose the walnuts were dropped by either magpies or crows. There's an endemic murder of crows around the bus station, which is just one kilometer away. They routinely scout the area.
