Asking or demanding?

My husband doesn't demand that I do things for him, and I would dislike it if he did. What he does do quite often is come into the kitchen and put the kettle on to make a cup of tea, for then he'll go back upstairs and carry on working, and forget about the kettle. When he does this I finish making the tea and take it up to him, and he's always quite pleased, but it's not something he demands I do.
