It is a bit like a restaurant that is a bit too hip and too expensive for its own good, but you give in to the hype to check it out, the food is not bad, but not really worth the price, and you are left at the end of the night not really feeling as though you wasted money, but absolutely sure you are not going back. Or maybe skydiving— or any activity you do once, you are happy you did it, but you would rather not jump out of a perfectly good airplane ever again. Or maybe a fun date with a nice person, but not someone you want to go out with again.
