Rust is a must if it's been standing for a while...for a...uhhhhhhhh...very... l o n g ...while!
Crusty isn't a word one would likely want to use describing something that is wonderful but it goes with rusty and is quite beautiful!
Musty is another word that seems...wellll...
not something you want in your cupboard but comes with...rust - and now the whole truth has been uncovered!
but can it can be said...in the same breath very quickly "rusty-musty-mushrooms-on-a-crust," and now it becomes almost edible!
It's also found in old garages...where old men sit swapping stories like in those funny all male lodges...
I Will Love You, Bob Orsillo
and help you in a transition when you don't know the next step or not wanting or caring just feeling inept...
Damp places is where it is normally kept...with plenty of salty sea water shout Hooray Hip Hep!
It can be many things to many people...like tall rusty colored trees where you can picnic, stretch and be extremely at ease...
or go on an adventure in an rusty old launch...
and then beach combing - finding plenty of shells and a very large conch!
