i just recently got back from Florida 2 months ago. From being somewhere when it is almost always freezing Florida is a great vacation spot. But this time when I went it never felt like a vacation it never felt like a thrill. We done all the fun things you would so on vacation, go to amusement parks, go to carnivals, go swimming, get tattooed and eat at places you never been before. But this time it never felt like it did the first time we went to Florida.
The phrase you mentioned, definitely relates to me not finding Florida vacation a thrill anymore. As a kid I was blinded of all the chores that you would have to do to keep on top of things and I guess simple "adult" things. So my perception has definitely changed.
Its funny what you mention, I think it has happened to me a few times. At some point you out-grow a place, a sensation or a person (not because you are better or worse, but because you simply differ from that person you were when you enjoyed their company), and puff, you are just not interested anymore in visiting the place, conversating with the person or wanting to feel like that again, I agree 100%.
