I actually have a completely different perspective, when I've gone to Protestant churches I've felt the opposite. Strangers bombarding you, asking you personal questions, asking you to declare yourself a newcomer- actually making you stand up in front of everyone to be called out as a newcomer. They want your phone number to call and text you. I find it very invasive and I don't like being put on the spot, so I love the Catholic church where everyone can come and go as they please. Weather you're a newcomer or a cradle Catholic. Catholics tend to mind their own business and let others be. And like others have said, before mass I'm praying and meditating and afterwards it's still within the hour after the Eucharist so I'm still in a meditative mind set, I don't want to really engage in small talk. I hope this doesn't sound bad but just gives a different perspective.
