I was all going to propose on a trip to Vegas. I wanted to get a gondola ride at the Venetian and pull the ring out there. But early in the weekend she said "Everyone at work thinks you're going to propose this weekend. Ha ha isn't that funny?" And we were in the World's Largest Gift Shop she picked up an enormous novelty ring with a plastic "diamond" about two inches wide, put it on and said "Shoud I show this to everyone at work?" So I was all "Shit, she thinks the notion of getting engaged now is ridiculous," and I just walked around with the ring in my jacket pocket all weekend.
I finally proposedl something like six weeks later, on a rocky beach on Tilghman Island, on the eastern shore of Maryland. Later I told her about the Vegas thing and she felt kind of bad about it.
You know, when I saw the movie "Meet the Parents," it kicks off with the guy all set to propose to his girl, then needing to back down. It IMMEDIATELY turned me off to the movie, and I found it cringeworthy all the way through as a result.
