"They were not necessarily close; more claustrophobicely bound."
Does that make sense? It does in my mind, but it might sound wierd.
It makes impossible sense, kinda like how oxymorons make sense. You'll be fine so long as anyone reading it is capable of using a substantial part of their right brain.
yeeeeeessssss
I knew i was smart.
Ahem, it would be "claustrophibically", NOT "claustrophibicely", but apart from that, very good indeed.
