"Would you like me to..."

I've never known anyone who had that reaction to that phrasing and it's interesting to me.

In my teens I became conscious of my own tendency to reply with 'no' to questions in the form, "Do you want...." When I was young, our family was not poor enough to be deprived, but getting things you wanted rather than needed was for birthdays and Christmas and sometimes not then either. All these years later and with full knowledge of how it came to be, I still react sometimes rather than take the question in the informal way it's intended.
