I am about to make hot cross buns and DH is going out to get some ingredients. We need butter, but are currently (no, I'm not going there ...) arguing terminology.
I say it's a 'pat of butter'; DH says the correct term for a block of butter is a 'brick'. WTF?
Please reassure me that butter comes in pats, not 'bricks'?! 
Hope you're feeling the importance of this one, btw ...
