My wife is being unreasonable. Need advice

[Telemon]

Greetings from frozen England.
I need advice. My wife is being unreasonable.
I’m playing SH3/GWX and I’m trying for full realism.
Last night it dawned on me that although ‘in game’ it was Feb ’40 in mid Atlantic with 15mtrs + winds here was I sitting in my warm (60F/20C) corner in the lounge with bikkies and hot cocoa to hand.
This was not right, not real, faked, I was a hypocrite!!
I went upstairs and put on my cold weather gear, sou’wester and rubber boots. Came down and opened wide the patio door. This was more like it. minus 4C and a bit of wind and snow. Soon there was a film if ice on my cocoa. But it still didn’t feel quite realistic enough so I asked my wife to go out and fetch a bucket of water from the pond and throw it over me. This was it; true realism.
For some reason now she’s a bit niggled, sniffling and the silence is deafening.
How can I convince her that we submariners take our game seriously?
