You can't get too attached to anyone
No one is from here, and no one stays here. Like a nightclub no one goes to anymore, most people will fail out of Vegas after a year. If they make it a year, they might make it five. Once they hit the eight-year mark though, they're out – because anything longer than that means they're a lifer, and no one wants to be a lifer in Vegas.
This is the world capital of Peter Pan Syndrome
People don't come here because they are responsible, mature, upwardly mobile, professionally ambitious, future-oriented adults. They come here because they want to live in a place where they can make a six-figure salary bartending and blow most of that on poker and strippers. They come here because they want to party until dawn every weekend and not be judged for it just because they're in their mid-30s. This is not a "marriage material" kind of place, but just in case, we do have drive-through wedding chapels. That's one way to avoid dating.
