Her: no I'll be ok with her thanks. Already made rice and lentil soup last night so she has dinner to eat, thanks.
Mmm, mmm, good! Rice and Lentil soup, the kid must be drooling. I think DD may be phoning soon to ask you to come rescue her from the meals! Btw, nothing wrong with offering to help her out, that's co-operative parenting. There may be a day when you're sick and need her to give you a hand. But, if she doesn't want you to take DD early, why does she want to come over?
