SC statewide primary and absentee voting

SC's 2020 primary for local elections is on June 9. Because of the pandemic, the state is allowing anyone to vote absentee (for the June primary only).

The Absentee Voting instructions tell you to download the application and mail it in. After receiving it, they'll mail you a ballot. Then you need to fill out the ballot and return it by mail again (or personally take it) to the county's voter registration office.

I'm not sure I would trust using an absentee ballot for the November election. But for the Democratic primary, there are only 2 seats for me to vote for, County Sheriff and Coroner. So if there's any snafu in the process, it won't bother me too much. If we end up being able to vote absentee in November too, at least I'll know how it works.

So I clicked the link to download the application. It presented me with a page requiring me to enter my details, and I thought, oh great, the application can be done online after all rather than needing to print and mail it in! But no, upon clicking Continue, it gave me a PDF file to print out. So you need to be sure to do that step early enough that there is time for 3 mailings back and forth as well as time for them to process the application, before the election date deadline.

I wonder if there are any cases of fraud where someone else enters your details for downloading the application (it requires your date of birth and last 4 digits of your SSN), but enters another address for the ballot to be mailed to. So that when it comes time to vote, the polling place doesn't let you cast a vote because you were supposedly mailed an absentee ballot which you never even knew about?

And what happens if you receive your ballot by mail ok, but for some reason you decide it would be better to vote in person - are you still allowed to do so, or not?

The above SC Absentee Voting informational page indicates at the very bottom (which I missed before) that when returning the ballot by mail, you need to have someone witness it. Power of Attorney is not required. It doesn't say if the witness needs to provide a signature.
This other page only says "Sign the return envelope in the presence of a witness".

So that's another consideration - don't apply for an absentee ballot if you won't have anyone around in order to witness it when you mail it back.

dog logic

I figured something out today which I had noticed a few times before, but didn't understand.

The little dog doesn't like the vacuum cleaner. When I start vacuuming in a room she is in, she runs out of the room if she can. The big dog, Zorro, doesn't usually seem very bothered. She only moves away when I come very near. But a few times, she has started following me around.

Today as I vacuumed the den, she was in one corner between the sofas. Rather than turning the vacuum off to let her get up and walk past me so I could do that corner, I went the other way to vacuum another room first.

As I was vacuuming that room, she walked in and lay down on the side I hadn't done yet. I had to tell her to move so I could vacuum there. Then as I continued on into the other rooms, she kept following me. Not directly by my side, but keeping a bit of distance.

On days like today, I can tell that she doesn't really like the vacuum cleaner noise - by the way she holds her head and ears and by how tentatively she moves. So why does she follow the vacuum cleaner around instead of staying away? I think she must have been in her "I'm afraid of that noise, let me get close to the humans so they can protect me" mode. Even though the human in this case is the source of the bad noise!
