My husband and I disagree over my use of the phrase "Do you want to ..." when I'm asking him to please do something for me, for example "Do you want to sweep the floor while I do the dishes?" or "Do you want to hand me that Coke?"
To me it's an expression that carries the meaning of asking him to do me a favor, but he's not familiar with this and it sounds to him like I'm literally asking whether he wants to do the thing. So I'm trying to figure out if this is a real, known usage, or simply a weird turn of phrase I or my family developed somewhere (it's possible – I'm autistic and my family is pretty unusual).
Is anyone here familiar with this usage?
