I think that a lot of those people likely live in a very car dependent, suburban area, and therefore don’t get any regular interaction with people outside of their immediate family.
I live in a city, so I have regular infractions with people that I know when I’m out and about: I pop into the butcher shop, coffee shop or green grocer and talk to the employees I know. I walk the dog, and run into friends and acquaintances that live the next neighborhood over, etc. People in rural areas usually have similar sorts of relationships with people in the area.
Contrast that with the suburbs, where neighbors may know each other to say hello to, but not much past that, and it’s hard to build any kind of relationship with the barista at the drive-through Starbucks or any employees at the local Kroger superstore.
I usually buy pea protein from MyProtein online. I personally find whey proteins to be way too sweet. The only issue is that it’s thicker, so I need to use a blender, rather than one of those shaker cups.
Find a basic flavor like vanilla, and add fruit (usually banana for me.) You can add a non dairy milk of your choice, if you don’t want to use water. Soy milk works well, and has bonus protein.
