We all have a very diverse groups of friends. Friendships between people of different backgrounds can be UN meeting or a cultural exchange event. The last thing you want is something that might seem small to one party turn out to be a major issue. Whenever there is a lack of understanding or just plain ignorance you never know what you are going to get.
Maybe you don’t mind when your black friends talking about finding you a white girl to get that good credit. Funny but not so much if said from one of your white friends. Maybe you don’t mind your white friends joking about locking their doors as soon as they hit South East DC or hit any boroughs outside of Manhattan. Again funny but not if said to a black friend.
These are very elementary examples and game of life is more complex but you the idea. There are somethings you just don’t say. Even if you are friends. Now if you guys are really friends than you owe it to them to have a talk before you blow up.
