He talks to me about them nearly constantly. He asks who would order them. He asks me to look up suppliers and manufacturers.
Today he found some that were pretty similar to the ones that he needs.
He just made me do a writing test with them.
And every few minutes he comes back out with permutations of pen casing and catridge so I can participate in some sort of ad hoc blind test.
They're his pens.
I don't use them.
I don't want to use them.
Why won't he just leave me alone about this whole pen refill thing?
