I have amused myself somewhat with contemplating the different scenarios I could present following a title for this post like “Last night, guess what”.
Predictably boring, I went for the above and the risqué-elaborative content I will offer is that exploiting the hook-up (electricity supply) with glee, I lay under the fan at 22:30, in-van temperature of 28 deg, with the setting to bring air in, and only on 20% the cool air flow was delicious. The context – see post re heat – is all, and at least the fan does do what the investment hoped for.
