Answer and Explanation:
Pam is a middle-aged, divorced real estate agent. This shows that Pam has some experiences in her life, as a person who has been through a lot and it seems that she is still dealing with these things, facing the problems of the past. Pam knows a lot of people, because of her work, she seems more thoughtful and rational than Martha and therefore, some people may think she is a flat character, but pam is quite profound, mainly in relation to her thoughts.
Martha, on the other hand, is a younger character and seems inexperienced, but we know that she went through something very serious and is running away from it. She is very careful with the answers she gives and the way she gets it and it shows that she is afraid to reveal who she really is, as this refers to the situation she is trying to escape from, Martha seems like a deeper character.
