Here we don't say bathroom, when we mean toilet. We say "toilet," as in, "Where's the, ah, toilet ?" Builders here know this, and the answer has always been, "Up the hall, second on the left." Certain foreign builders apparently don't know this, & the result has led to a great deal of confusion.
I think in England they say "lavatory," or "lav." As in, "Where's the lav, luv ?"
Sometimes people here say "dunny," but that just means they're not really interested, & anywhere in your backyard will do.
Personally I encourage people to void their bladder or their bowel in the correct facility, but I'm ready to admit : I'm fussy like that.
So it was quite a surprise when recently, during a bar-b-q over at one of Barry's mates', I found myself in a very small room with a gigantic winged reptile. It came at me with unnecessary force, before I'd had a chance to unzip, even. The result was a general wetting of the crotch area, and a bit of a bruise ~ no, let's call it what it was ~ a 24-stitch slash across my throat. There was a fair bit of fluid involved, and a good deal of the other as well.
I found my way back to the bar-b-q, clutching my neck, trying to get Barry's attention. I was thinking a quick trip down the road to Emergency, at least a tetanus shot might have been in order, but Barry assured me that the thing in the toilet hadn't been around for 150 million years, so I settled down a bit, and opened another beer.
Things were something of a blur, after that, but Barry got me home and tucked me in. He's a good mate, old Bazza. Some of his friends are a bit weird though, I reckon.
