This is indeed what missionaries do.
I think the elders in my ward have adopted the idea that they can just come over to my house unannounced and ask for dinner. Because that is what they do. They just show up. And then they're like "uhhhhhhh... we're hungry"
Once my dad asked what lesson they were going to share and their mouths dropped like
"We have to share a thought?"Yes, yes you do have to share a thought. You're missionaries, that's your job.
So they flipping brought out 1 Nephi 2:15
If you don't want to look it up, here it is.
"And my father dwelt in a tent"
Yep.
That is the scripture the missionaries hit us with.
Just let that sink in.
