High and Low Self Monitors

My cousin and I were recently discussing High vs. Low Self Monitors and how they deal with each other. Firstly, a high self monitor is someone who cares a lot about how they present themselves, how they interact with others, and keep in mind other peoples' feelings. Low self monitors, on the other hand, are more concerned with self-expression, their own feelings, and do not care as much what other people think. This isn't to say that low self monitors are self-absorbed, it just means that they don't care what others think of them. 

Often, a major difference is buying habits. For example, lets say we have a couple who have been dating for about a year, Lisa and Tom. Lisa, as a low self monitor, loves simplicity and does not see a reason for buying superfluous or luxurious items. Tom, as a high self monitor, likes to buy nice things, however, he sometimes overindulges. Tom loves that Lisa keeps him grounded and likes hearing "do you really NEED that?" 

On another note, low self monitors may unintentionally offend people. As another example: Tom invited Lisa over for dinner. He spent hours preparing and cooking their meal. When Lisa got there, they sat down to eat. Lisa took one bite and could not control the look of disgust she was displaying. She immediately reacted, saying "that is awful!" This really hurt Tom, and Lisa didn't realize she was being perceived as rude. See, high self monitors take the self expression to be impolite in many cases, where the low self monitor believes it is "insincere" to not say what they are thinking, or to tell a white lie to save someone's feelings.
