Have you tried looking down the back of the settee? I find stuff there all the time, but I don't recall as yet finding a prime. Some things have been pretty ripe though, but that's beside the point.
The other place I find things is in the last place I look. Somehow, everything always ends up in the "last place". I don't know what it is about the last place which causes it to attract everything in the universe towards it. Perhaps it's a black hole of some sort. There must be plenty of primes in there by now.
Also, what is the 'see' language of which you speak (I assume it's an abbreviation to match all the other cryptic single letter usage). Is that something to do with looking with your eyes to find the prime?
Or maybe it's the 'sea' language. Maybe, there are a prime number of oceans after all.
