Part I :
Guests
More guests
And even more guests!
Brownie points :
Special food cooked at home. 
Home would never look so neat & perfect in every possible way.
First class.
Turn offs :
Thrown out of your own bedroom to accommodate them.
The talks about what you do.
The impossible- to- miss-stares after you tell them what you do.
The calculation their heads are doing to define the appropriate time for marriage (of course for you) - which is anything less than half of what you might have planned for yourself.
Self-praise. Too much.
PART II :
 Cultural Laxman Rekha  
Thesis :
No night stays @ friend's place.
No partying. 
Guys not allowed to enter home.
Talking on phone with guys restricted or nil in some cases.
Books are friends. Why hang out ?! :-|
Issue :  Virginity , I assume ! :P 
Brownie points : seriously ?? None what so ever.
Note : Most cases of eloping are a result of ones daring to cross this 
Laxman Rekha.
Most cases of guys getting spoiled too would fall in this area.
The more you restrict - the more boundaries crossed.
PART III
Marriages
Love marriage is an alien territory. 
Typically the 
vices for our folks are :
Smoking. Drinking. Eating non veg.
And the fourth is - Love marriage!
The tedious ridiculous process in history of marriages : Arranged marriages!!
Check each other out. Read bio data. Interests and other such things.( Most of which are written just for the heck of it  :P ) 
One hour of rendezvous.
Few days time for approval--- without going out on date or contacting each other!!
WTF !!
PART IV 
 Weddings
 Turns offs :
Read Part I  +  pretense  in every whichever way , in every whichever section.
Brownie points :
Get-togethers. Time off with cousins.
 The various functions which don't make much sense :P but fun to be a part of.
PART V
Miser ??
Stereotypes are stereotypes.
Definite believer in  : If you have it , flaunt it.
Reference : Diamond obsession . 
Reason : Competition :D
Baring apart few , most of the rich ones  live luxurious life et all. But they're misers in some areas. 
Indulgent lifestyle.
PART VI
Family
 Joint families > Quarrels > Partition > Nuclear families.
a. Nuclear forever.
b. Nuclear yet bond with extended family.
c. Nuclear , bond with extended family , relatives , society..etc etc :O 
Joint families ? - Extinct species. Fun. Pros & cons.
PART VII
Religious Values
Don't question. 
Just follow. 
Believe.
(  Personally I have no issues :P )
PART VIII
Passion
Business is in the blood.
Money. 
Stock market. 
-----
Overall ..business families. Highly conservative. Typical Ekta Kapoor serials in some cases !
They want girls to get best education. But to not work after settling down into another family. ( ???! )
Baring apart the unnecessary illogical immature social and cultural rules our folks have  : Marwadis are nice people :P  
I always warn my friends not to fall for marus. Life after marriage in marwadi family is kinda difficult :P
