Mum & money

Perhaps she feels it’s their way of contributing, if you are cooking etc?

Maybe years ago they were the ones doing all that.

If it makes her happy to give you some cash towards the meal, I would thank her and accept it graciously, but say there is no need.

Their company is what you want.

Perhaps they have been used to giving you money for things in the past. I often offer to pay for my son's train ticket etc as he is having problems at the moment.

I don't think you should feel hurt, maybe they were of a generation who found laying on a very nice meal for guests would be a strain on the finances. Aside from that aspect, guests often bring contributions wine, chocolates anyway. Just thank her say "I appreciate the gesture but I don't need it".

Enjoy the lunch regardless.

I think your Mum is simply being gracious, giving and thinks this is a nice way of thanking you.

Accept the money in the spirit it is being given.

Would she normally have brought something like a pudding or a cake but doesn't feel up to doing that now?

Please don't be hurt or offended or tell her tgat you are. Xx
