Seems fine the way it is to me.

The top portion of the time machine meme is superfluous, that's why its always the same. Its not actually saying anything about what girls would do with a time machine, its just a framing for silly ideas about what you might do with a time machine contrasted with a mundane use.
The "what girls think" meme probably stared as more of what this image is referencing, but similarly is now (in my experience) more about highlighting something silly by contrasting it with something more normal or expected.

Yeah, mate, I wouldn't hinge a lot of assumptions on the basis that idiots are a myth.

What leads you to believe this is bait?

>weight loss in general is a myth
That's one hell of a take.

Yeah, that's fair enough. I get the feeling the words themselves might be to broad or vague to dive this far in to them anyway.

"you most likely met many introverts you never even realized were introverts."
I'm talking about people I know who fit the definition to a tee, how do you normally identify introverts and extroverts?
"Personally, I find many of the qualities of an extrovert annoying but I can also realize how they could be positive."
Same.
"So maybe spend some time listening to others opinions on the subject and try to keep an open mind."
Haha, I'm doing that right now.

I think the qualities that make an extrovert are generally positive while the qualities that make an introvert tend to be negative. This is from experience, not strictly definitional. For example, in my experience introverts don't have a tendency to think more deeply than extroverts, they just tend to share their thoughts less. As another example, very few extroverts I've known have had great issue with being alone or doing things alone, while almost all of the introverts I've known have had some form of social anxiety.

Why does it mean that?
