Sense and Sensibility #4

I have noticed one thing about this book: it has lots of characters. I feel like there are so many people introduced in the story that it is hard to keep track of who is who. Lots of times when I read, I find myself needing to go back and think about who the speaker is and what the situation is a second time. The fact that they are mostly all referred to as "Mrs. and Mr." does not help out either. I am understanding the book, but I just found the number of characters as a speed bump in my reading.
