The first example is their likes and dislikes. Vince is very good with mathematics and numbers but on the other hand Mac is not as good. For example at their business in The fourth stall Vince keeps track of all the money and all the books but Mac listens to people’s problems. Another difference between Mac and Vince is Mac isn’t a fan of school but Vince is a little different he enjoys school . For instance, I read that one time Mac started daydreaming about one of the big problems he had to solve, in the middle of class.
They also have many similarities, one of them is they both LOOOVVVEEE the Chicago Cubs. They love them so much they do cubs trivia with each other at random times. Another similarity that Mac and Vince have is that they both are good at solving problems .For example, when they have to solve a problem they always get to the bottom of it. The last similarities that Mac and Vince have is they are both very brave and sneaky. One time they snuck into the principals office and changed the test scores.
In conclusion, Mac and Vince have their own unique personality. But their many similarities is the core of their friendship.
