It put me in a lot of puzzling and uncomfortable situations when I was young. When I was really young, like under the age of 9 I had no understanding at all of why they had this rule. I thought that there was something bad about the kids and their families, like inherently wrong that I might catch, so I felt a mixture of guilt and fear.
It was weird to have to decide whether to run away when they came up to play with me and the friends I was allowed, or to try to be nice to the but risk getting in trouble at home, especially when I had no idea why I wasn’t allowed to play with them.
When I got older and hung around with Catholic school friends outside the neighborhood who had Protestant friends then my mom couldn’t stop me from interacting with them.
My parents did what they thought was best and ultimately I don’t think it did me any damage. Of course the idea that Catholic kids and their families are automatically a better influence than Protestant kids and their families is erroneous. I was horribly abused, including sexually, at home and my Catholic friend’s dad had a HUGE porno stash that we were well aware of.
As kids we never discussed religion or anything so they weren’t much of an influence until I got into high school. At that point many things in my Protestant friend’s churches were attractive. They had more active and dynamic youth groups. Square dances, field trips, vacation Bible school. So ironically, when I was allowed to interact with them was the point when their faith had a bigger influence on me, but that’s just life.
The idea that because we were Catholic we were ‘better’ than others sort of messed with my mind, because I didn’t believe it and I wondered why my mother felt that way.
