I have trouble in understanding the meaning or the implication of "seven to four" in this sentence. I could not get any related explanation in the dictionary.
My guess is: I would volunteer to work for a free day just to see that look on Will again?? But why seven to four? If not, Could anyone help please?
The context is:
“I” am a medical carer of Will who is a quadriplegic in wheelchair, and I took care of him for two years and saw him in a lot pain. Louisa is Will's new carer recently hired. The two had just come back from a wedding reception the day before, and had spent the night in a hotel, only because both of them got so drunk on the wedding and nothing else happened( Will is a quadriplegic). The conspiracy in the text is referring to a trip the two persons are planning and later they were asking if "I" could go with them.
Here is the sentence:
Louisa looked a bit shaken but he had gone over and murmured something to her, and that was the point at which I saw it. She went kind of pink and laughed, the kind of laugh you do when you know you shouldn’t be laughing. The kind of laugh that spoke of a conspiracy. And then Will turned to her and told her to take it easy for the rest of the day. Go home, get changed, maybe catch forty winks.
‘I can’t be walking around the castle with someone who has so clearly just done the walk of shame,’ he said.
‘Walk of shame?’ I couldn’t keep the surprise from my voice.
‘Not that walk of shame,’ Louisa said, flicking me with her scarf, and grabbed her coat to leave.
‘Take the car,’ he called out. ‘It’ll be easier for you to get back.’
I watched Will’s eyes follow her all the way to the back door.
I would have offered you seven to four just on the basis of that look alone.
