Welcome to the internet
Put your cares aside
Here's a tip for straining pasta
Here's a nine-year-old who died
We got movies, and doctors, and fantasy sports
And a bunch of colored pencil drawings
Of all the different characters in Harry Potter fudging each other
Welcome to the internet
Technically, it's not upvote begging. They're just saying that if it somehow gets 10 upvotes, it gets a part 4. They never ASKED if they could have upvotes, only commented of a reward if they chose to.
It’s actually because I can’t tell if you guys are interested without some kind of sign. When online, you’re pretty limited when it comes to showing interest, so upvotes are a good way to do so.
