It never occurred to me to think about decoding firewood collection behaviors from the archaeological record—reconstructing species burned from the charcoal/ash, yes, but not all the collecting as a social behavior.
I’m pretty sure Sebastian the Ginger Cat has never thought about firewood.
BTW, the Spanish for firewood is leña. It’s not in the typical travelers’ Spanish vocabulary list. Translations of beer, toilet, laundry, please and thank you, yes—but not firewood.
