I would save hundreds, maybe thousands of dollars by spending the entire time walking in and out of places that I want to visit which have entry and transportation fees. Onto boats, into parks and museums, movies, operas, etc. The last thing I would do that day would be get on a red eye flight to somewhere far away I'd like to visit, timed so I wouldn't become visible again until after I get off at the destination in the morning. I might never get a chance to be invisible again, so I might as well be as efficient as I can with my fun.
A stately pleasure dome, wasn't it? (I promise I'm going by memory and didn't look it up--give me the answer!!!!)
I'll copy Qlip and ask, "What bird did the ancient mariner kill?"
I've not read that poem and I don't intend to but I'll hazard a guess at albatross or seagull. Albatross is more poetic. Seagull is... sea-ier. Or maybe it's some bird I've never heard of. Like puffkins. Are those birds. Or are they pokemon?
