I remember the margarine with the yellow blob that had to be worked into the white grease and it was in the 50's! When I asked my mom why we had to eat that crap, she said because real butter was too expensive. I said that I didn't care how poor I might be but when I grew up we would only have real butter in my house. I stuck to it.
To make life easier, my grandfather bought me a pound of butter every Christmas. I'd make toast all morning long and share it with everyone. I felt like a princess.
