Difference of opinion, what do you think?

Yesterday at work we were having a discussion about Mothers Day, which is tomorrow in South Africa. We were discussing what we were going to do, what we would like and what our ideal mothers day was. One of our staff members also has her mother in laws birthday on Sunday, so they are having a big lunch with her husbands family at her house.
 Her own mother was invited to the lunch but has chosen to go to my colleagues brothers house for lunch, where she will see the rest of her children. So, my colleague will not see her mum in the day. My colleague mentioned that she will pop around to her mums house in the evening and her mum will cook her dinner. One of us suggested that why doesnt she package up some of the left overs from the party to take to her mum and they can use it as a sort of picnic supper to stop her mum from having to cook on Mothers day.
Well, a heated discussion about the propriety of this ensued. A few felt that this would be lovely since they would probably all be tired and then nobody would have to do any cooking. And that her mum would probably appreciate the gesture and being thought of and that she didnt have to do any work. The rest felt that this was inappropriate since it was left over food and that her mother would be offended, so she should let her mum cook. This group felt her mum would feel that they did not appreciate her if they bought left overs. The left overs in question were going to be roast lamb, potatoes, veggies, dessert etc, a proper meal, not finger food.
Of course, this got me thinking about what is right and what isn't. Personally I wouldnt mind if my daughter bought food over to me to save me from cooking, but maybe it is not right, so what are your thoughts about it? Would you be okay  with it, or would you be a bit offended?
