What I Would Say

 If I had a chance to talk to John, I would tell him to become a little bit more mature. For example, first thing I would tell him is to stop smoking and drinking as much. I would tell him to be more responsible. I would say that he needs to listen to Lorraine sometimes.

I would tell Lorraine, to be a little bit more relaxed. Like she freaks out about every little thing. So that's why she needs to be a little bit more laid back. It's good that she's responsible but she needs to dial it down a little.

So overall, I like how the characters are but they just need to change a little bit. Like John needs to be more responsible, and Lorraine needs to relax a little. If Lorraine wasn't Lorraine, John would be getting in a lot of trouble. So that's why they both need each other.
