DP's pedantry is really getting to me.
I spent a lot of time abroad and once accidentally used the American spelling for "gray". He knew what I meant. He knew I was picking the grey shirt. But yet I got a "?" and "did you mean the grey one?".
We know precisely ONE Cate. I was talking about going over to Cate's house for brunch as I do fairly frequently. Every time I get "Cate?" Hardly Cate Blanchett's house is it!
I have a friend whose name is pronounced an unconventional way. I say it the way she says it. Every time I bring up this friend he corrects the pronunciation to the "right" one. Sometimes he talks about how phonetically the way she pronounces it doesn't make any sense.
We have yet another delivery coming along next week. I said it's scheduled to arrive at around 1. He says I need to specify if it's 1pm if it's an afternoon delivery because "who knows". 
Every discussion basically devolves into an argument about semantics, it's boring.
YABU — This would not bother me.
YANBU — I couldn't date someone this pedantic.
