Need an activity that helps improve your conversation between the two of you? Try Fishing, fishing allows plenty of time to get to know each other again. You most often have long periods of quiet time that allows for conversation to fill it. You don't see people just sitting quietly while they are fishing. This makes for a great time to talk about something important also. You are usually secluded in a way from the rest of the world. You can be on the banks of a lake or out in your boat and it is like you are the only two people on earth. Sure you will have to cast or reel in a big fish from time to time. The conversation time is all the time you are waiting for these things to happen.
So if you need to talk or just get reacquainted, grab your fishing pole and some bait and head out to the lake. Most likely you will come back with a better understanding of each other. Plus fishing is rated as one of the most relaxing things you can do, so it has double the benefits.
