Who says there is plenty of time to get know them after were married?

Chapter please?

It was Charlotte Lucas, talking about Jane and Mr Bingley .

You have to bear in mind that Charlotte was about 27 years old at the beginning of the novel, she didn't have any kind of expectation about getting married, far from she didn't have prospect than to be a sole burden for her parents.

In chapter 6 she tells to Lizzy "When she is secure of him, there will be more leisure for falling in love as much as she chooses".

The quote is referred to Jane and Bingley, although it explicates also the choice she made concerning Mr Collins.

Usually, she is seen as a resigned girl who just accepted that idiotic Mr Collins, but she is uniquely practical about marriage and life in general.

She puts the security of having a husband, a home of her own and a possible child before love, in addition to this, her younger sisters can debut in society and seek a husband on their own.

The rule was: the older sisters attend balls and social events to find a husband, afterwards, the younger sisters could introduce in society.

The Bennet family didn't follow that rule, they were all out there, from Jane( the older) to Lydia, Kitty and Mary (the younger), all of them attended social events at the same time.

This caused some kind of perplexity in Lady Cathrine De Burroughs mind, which Elizabeth explained in the calmest way by saying it wasn't fair to punish and not allow some fun to the younger sisters because the oldest aren't married.

In the end of 18th Century through the Victorian Era, love was a sole matter of chances. Loving someone wasn't supposed to end in marriage, marrying someone didn't mean loving the chosen one, as long as there were respect and wealthiness, everything would turn out fine.
