When I read stories of mathematicians -- for example, "Fermat's Last Theorem, the story
"They gave their beloved wife the completion of the proof"
appears.
The story of a mathematician, appears quite often.
However, I,
"It scares me that the thought that they can think that their wife would be 'happy' to receive a gift of a mathematical proof"
-----
Oh, I don't think so.
"Farewell to the days of their husband's inexplicable eccentricities(Muttering, walking around)"
That's a "gift," for sure.
Then my wife will be happy.
