Wheel of Fortune with your partner
A quiz show is a good way to spot the gaps in what each of you knows. I mean it, and it is funny.
Play it together
Put on Wheel of Fortune, or any quiz you both enjoy, and play along out loud. Within a few rounds you will find the gaps in what each of you knows.
See the funny side
The gaps are the fun part. Nobody needs to be right. A partner who gives you the freedom to be yourself builds even stronger trust, and laughing at what you do not know is part of that.
Why it works
Men do things together but do not talk about it. A quiz gives you something to do, and the talking happens on its own.
Talk it through
The SI guide can help you think about your own version of this. It is not James, and not a professional of any kind.
