I just spent part of the morning checking words to see if they should be written with or without spaces in English, so I’d be lying if I said I knew the rules about it. I rely on my instinct. Sometimes, two answers are right.
At the DIY store
Woman: Oh look dear, a nice bath mat for the bathroom! Do you like this one?
Man: Geez woman, can’t we just get a shower mat instead? I mean, look at the price!
Woman: I think it’s nice, written in English and all. Very chic.
Man, shaking his head: I should have never agreed to put in that bathtub in the first place…
Woman: You should be happy I didn’t convince you to install that hot tub I’ve always wanted!
