I don't think I'm greedy....I'm a slim person...size 10-12 UK and 5 foot 6.
I don't binge or anything but when I eat a roast dinner, I do want more than 2 potatoes!
When MIL cooks anything she always seems to underestimate amounts....so there's for eg 2 potatoes per adult and one per kids...not a lot of meat and two other vegetables....curry...she'll do enough rice so people get two dessert spoonsfull.
That's not enough is it?
