Great Expectations question

Why is it that Mrs. Joe is polite in public, but when she is alone with Joe and Poe she becomes a sort of military Sargent, who yells and hits them? The author points this out when he writes "My sister was uncommonly lively on the present occasion, and indeed was generally more gracious in the society of Mrs. Hubble than in other company." (23. Dickens)

Paragraph Conclusion

I'm leaving out the transition sentence because I'm not sure how it will work with Mathew's paragraph.
    In this play lies are used in multiple ways, but in the end it boils down to what you can gain by not telling the truth. There are so many ways to be dishonest but it seems that the most useful methods, at least in this book, are perhaps lying in your marriage or possibly trying to get out of a sticky situation, but most of all trying to pursue your personal, singular gain. When Wilde shows us this extreme use of lies he is trying to show us that everyone is dishonest. It's how we live, its how we survive as people in the lives that are given to us.
So it appears that sometimes it's not so Important to be Earnest.

 I edited my paragraph so that it fits a little better. I wasn't quite sure what to about the first point. Let me know what you think

The Importance of Being Earnest Paragraph

In general, lies are bad but in certain situations they can be beneficial. Take avoidance for example, dishonesty can help you get out of just about any situation. That’s not always a good thing, but Algernon certainly takes advantage of the power of lying when he speaks to his manservant. Lane is aware of his master’s lies but intentionally goes along with them to keep him out of trouble. This exact circumstance arises when the play first begins; Algernon discovers how much wine was consumed the previous night and blames it on the servants. It seems that Algernon does this to retain his pride, to somehow prove his high standards by denying the fact that he gets drunk. Another incident that Algernon avoids something in is when Lady Bracknell arrives requesting cucumber sandwiches. His response to her is. “Good heavens! Lane! Why are there no cucumber sandwiches?” (Algernon Act 1) Of course, Algernon knows very well that he ate all the sandwiches, he is trying to stay on good terms with his aunt, by avoiding any possible arguments between them. This in a way proves that although he is a hoddy proud man, Algernon is also afraid of something, confrontation. Still, Algernon isn’t the only one who avoids certain situations; Jack is also guilty of being evasive. He prefers to avoid his responsibilities. Or more specifically his duty to be a role model for Cecily. Instead Jack prefers to run away to London, pretending to be his nonexistent brother Ernest. By doing so he is not confronting the fact that he is a man now and must grow up and face reality. Although lying to avoid problems can be beneficial now, it can come back to haunt you in the future, Ernest shows us this.
