It might be a good idea to get explicit directions instead of making assumptions about what someone wants. Richie told two guys working for Christopher, "if there is anything you can do for me let me know." Since Richie made a negative comment about Christopher they took this to mean that he wanted Christopher killed. It was a big leap and a colossal misinterpretation of intent. (Also, if someone is keeping their back to you when they are being introduced that should tell you that you really do not matter to that person.) When you are trying to climb the ladder of success it is important to understand the correct and proper ways to behave and don't try to advance too quickly. You can't start at the top.
Don't give gifts that are important to you unless you know the person who is receiving truly wants the gift. Richie gave Tony a jacket that he truly didn't want and it was pretty obvious. Richie was trying to get Tony to see it as a sign of respect. But, he missed the queue that Tony really didn't want it. What Tony really wanted was Richie to show him respect by building a ramp on Beansie's house. (The same guy Richie ran over earlier in the season.)
Carmella decides to intimidate her neighbor's sister into giving Meadow a letter of recommendation to Georgetown. It wasn't what Carmella said but what she didn't that was intimidating.
