one of these things is not like the other

here is something that has always driven me crazy, or baffled me at least.
the definition of "adulthood" is different for many people. to some it might happen: on the 18th birtday, when one moves out from the parent's home, upon attendance to college, having the first "real job", turning "legal to drink"........you get it.
whatever you see the beginning of this phase as...do you ever notice how most people always give unsolicited advice when you tell them "what you are doing next?" i.have.always.hated.this.
it never fails, someone says, "oh - you're moving to (fill in the blank)?"
you say, "yes"
they say, "oh, it's much too hot there" or, "it's so cold there - you don't want to do that."
and you think "oh, thanks for raining on my parade"
this happens with nearly EVERYTHING in one's adult life and i don't get it. people always comment something negative or defeatist about life choices.
when someone is getting married they say "oh, are you nervous?", or "do you think everything will go off without a hitch?"
when someone is buying a house, "man, that's a lot of responsibility."
or when having kids, "man, that is a lot of responsibility."

it's like people don't have anything other than something blatantly obvious or generic to fill the silence or something. seriously, if we were all intended to live the same lives, doesn't anyone believe that we would have been created as little, controlled robots? as an adult you can choose to take on whatever you want or make your life look however you want. with every life change, i try to anticipate these nothing-better-to-say statements and come up with something equally as ridiculous as what the person just said.

Public Service Announcement for the week: say something nice or don't say anything at all. geez. give people a break when they are going through a serious life change and be positive.
