My partner still believes but sees the BS in religion. I feel she just can’t say she is atheist. We met after our kids were adults and out of the house. My kids are atheists though I never discussed religion with them. Her son is atheist and her daughter probably doesn’t believe (from our conversations) but is raising her kids Catholic because it is important to her husband who was raised in a very religious household.

I would assume for increased shelf life. This is German style potato salad and I have seen the cans in stores for at least 30 years.
