Replying to Question about going out

Alright, heres what I never understood, can anyone give me at least one logical reason?

Why is it that everyone insists on going out to bars, clubs... wherever you preffer, only after 10pm? Why do people go out on week days and start the party at 10 when they are working or going to school the next day? why not start at 8 or something?

1: Its cheaper: a lot of places have cheeper drinks at this time
2: no Cover charge: I have never heard of a place that charges a cover at this time
3: no lines: you get there at 10 and your in at 11... why not go there at 8 and be in at 8!?
4:get to chose your place: no assholes are sitting where you want to be... because they will be there at 10
5: not tired the next day: You have 2 hours more of sleep, or 2 more hours to party
6: you can actualy have more than a beer and catch the last buss and metro to get home.

heres the only reason I found why people go out late instead of a reasonable hour. Its cool! why is it cool? because it makes people look tough. "yah im going to party tonight Im going at 10, Il be back the next morning at 4 and Il go to work" Its true, if you leave early, everyone bags on you because your not tough and you should not care about work and just party. why not just party at 8 and do both?

theres my question... people give me logical reasons for going out so fucking late.... please
