The Constants of Partying In Vegas

This weekend I started questioning whether I was simply getting too old for this or what was the deal. The thought comes from the fact that I have become quite understanding of several things that seem to happen everytime we go out drinking in Vegas. So I have made a list of them just for the fun of it and I'm also curious if others would agree that these things are typical happenings when going out in Vegas or other drinking establishments of the world.

So here is my list of the constants when going out in Las Vegas.

A. Someone drinks too much and makes some extremely awkward conversation.
B. The group tab is always bad because people always end up stiffing on the tab.
C. Following up with B. some poor sucker such as myself ends up paying more than they should have had to to cover the tab.
D. Vegas clubs are over priced, over crowded and not really that fun.
E. There is always some macho guy with too much testosterone flowing that wants to start a fight.
F. Some dude always gets too grabby with random females.
G. You can never have a conversation with anyone because the music is too loud.
H. You know you're not cool enough when you have never heard the song playing but everyone else knows all the words.
I. The more the drink costs is directly proportional to how much smaller the drink is than a normal out of the way bar.
J. There is always one creepy old guy who seems to be really out of his element in a mostly younger crowd looking to accidently rub up against someone.
K. The person taking all the pictures doesn't realize how annoying the constant picture flashing is to everyone else until they are not the one taking the pictures!
L. At the end of the night your ears will be ringing so loudly that you probably couldn't hear the smoke detector going off if it was.
M. The person that you hoped to avoid will always find a way of showing up to the gathering.
N. When said person shows up there is never any waiting staff around for you to get another drink quickly.
O. You or one of your friends will always have to apologize for another friend by saying they just drank too much they're not normally like this.
P. There is always some random guy in the bathroom who is a little too chummy.
Q. Girls are never back from the bathroom in less than 10 minutes!
R. When you are in that bathroom you notice that the bathroom attendant has made more money in one night handing out towels than you have made in a whole week of normal work.
S. You never realize how little sleep you are going to get until you have to wake up really early the next morning.
T. Texting random people when drunk always seems like a great idea until the next day when you have to apologize for it.
U. Someone always disappears from the group without anyone noticing until an hour later.
W. A bottle of water generally costs more then a domestic bottle of beer.
X. Each time you go out there will always be something that happens that you could have never seen happening in a million years.
Y. Why did I stay out this late is one of the many questions you ask yourself in the morning.
Y. You know it's bad when there's a line to get out of the place.
Z. The next day you look at all of your receipts and your account balance and wonder was this all seriously worth it?

Well that's my A-Z list of the Constants that happen while going out... I'm sure there are more but I figured 26 would be good enough for now. There are definitely some things on the list that I'm guilty of but I'm just starting to think that I have seen these constants one too many times any maybe my going out days are coming to an end...
