It’s a pagan celebration co opted by the church to expand the influence of Christianity.
December 25th is not even the correct day to celebrate the birth of Christ. That’s other pagan holidays being co opted to fuel conversion of “Savages”.
Yule is not a Christian celebration yet it has been supplanted by Christianity.
Some reading on the practice.





I eat cheese on its own as a snack regularly. I never eat bread on its own without at least butter on it.
It’s enjoyable to eat cheese on its own so there is no problem here. And I would also have just put the extra cheese on the last piece of bread but it wouldn’t annoy me in anyway. The bread I would just toss unless I was actually hungry, but I’ve been eating cheese and bread all day so I’m not likely to be hungry
Bread is not good for many birds to eat.
This is a silly premise to begin with, but to answer it having an extra piece of bread left is the less desirable option
