I rarely floss because it seems like a lot of work for seemingly little gains.
I suggest you take a look at water flossers. Flossing, while a lot of work, is sometimes necessary when you've eaten something stringy that gets stuck between your teeth. Having it be stuck between your teeth for a day(s) will result in cavities and inflammation.
Lol, I didn't even get that far. Got either ignored or into an argument as to whether China and the CPC is or isn't communist just because I filled in that living in China and learning about Socialism with Chinese Characteristics was what introduced me to socialism. (not in the USA; applied to three)
Vetting isn't the issue, but they're supposed to provide you with the materials and the roadmap to joining. Not being a member of the party should preclude you from joining their open events and volunteering your time towards socialist causes.
