I think it was DSoTH’s early days here when someone offered that fly pattern to explain Sine’s name and Samuli liked that answer. If my memory serves well…
In my childhood here in Finland there was a sign on the local trains saying: “Älä sylje lattialle” och samma på svenska “Spotta ej på golvet.” I think that was a relic from times past when people used chewing tobacco.
Words that big are scratching my ears
