I accidentally fell into doing an experiment yesterday that I think I'll continue. It started just because I was saying "Hello" to people that I passed. After the third time that I consistently got a "Hi" back, I thought it was interesting. Since then, I've received five more "Hi"s and one "Hey". No one has said "Hello" back.
cindygerb thinks this is because "Hello" is more formal but I'm not convinced. I'm going to continue this and see what happens.
Unrelated to that, I seem to've developed a headache that I've never had before. I hurt on both sides of my head in about the middle third of my brain but not in the center of my head between them; probably right behind Broca's area but on both sides.. It's also not affected at all by light. My normal headaches (that I don't get -that- much) are in the occipital lobe and the front of my frontal lobe.
Here's a picture for those that have studied quite as much neurology. :)
It started yesterday morning really lightly almost as if my scalp hurt. But as the day wore on it got worse. It's made both concentrating and sleeping difficult. I wouldn't mind not sleeping so much if I could actually write or read non-fluff. Thankfully it hasn't gotten much worse since last night.
Note that I'm doing this to document it rather than sympathy or whining. That's why I used more technical terms that I would normally.
