Given the sign it's likely Mph. That's the correct size and font for the standard US speed limit.

Hah

That whole treasure behind the waterfall thing is sooooo cliche. But dangit if I don't get mad when there isn't something behind the waterfall.

See that really annoys me. It's a legitimate strategy to get followers. Just admit that it's a strategy and move on. We all know it works and if your using it as your source of income have at it. Taking offense because someone points it out is a bit like a football player taking offense when someone says they just practice or use a coach to win games. And for those that want to call those woman names or hate on them they need to get over themselves too. As long as it doesn't get explicit or comes with the appropriate warnings the only people that watch are those who know what they're watching.

The only acceptable cone.

Speculation. Truth is we don't know. However, there are alot of chemicals that we do know of that can do the same thing.

Then the best I can tell you is that you most likely met many introverts you never even realized were introverts. This is not uncommon since many of us are perfectly functional and even comfortable in social situations even if it's not preferred. As far as the qualities of an introvert being negative I think you've got a bit of shortsightedness going on. Personally, I find many of the qualities of an extrovert annoying but I can also realize how they could be positive. So maybe spend some time listening to others opinions on the subject and try to keep an open mind. I'm not saying you should change your opinions just be open to the possibility that some of what we said is also true.
