I feel like saying 'no, I've just asked you - it's now your responsibility to remember!'. Example, my DD's friend accidentally took home my DD's school jumper so I texted her mum (a friend of mine) asking her if she could get her DD to bring the jumper into school tomorrow to give back to my DD. Got a txt back saying 'yes, but can you remind me tonight as I'm not at home.' Why should I have to remember to txt again later?? What if I forget - whose fault will it be if she then doesn't remember!
Sorry, I am over-playing it a little but it just got my goat (and I'm a bit hormonal).
