Have you explored an abandoned building? If so, what was it like?

I grew up in a tropical island, and it was a (not well kept) secret that one of the resorts went bankrupt and was shut down. They kept the lights on and from a distance you couldn’t really tell there was no one there, and they had security guards patrolling the property… well, my partner and I, and young horny teenagers, decided it would be cool to sneak in and get naughty on the rooftop. That part was fun and all, but it was so cool to go through the empty hallways and rooms and play mission impossible when the security guards were nearby lol… I went back a few times to explore late at night, never got caught by any authorities thankfully 😅
