My Aunt recently posted an experience on Facebook that she had in a McDonald's.

A woman was wandering around, striking up conversations with random people in the restaurant. Even when the customers didn't want to talk, she would stand there going on and on. She then walked over to my Aunt's table and started getting very agitated, saying that my Aunt was at her table. The manager came out and asked her to sit down and stop bothering people, but she insisted that she couldn't sit down because my Aunt was at her table. The manager called the police and I'm sure she ended up in a hospital somewhere.

My Aunt said the woman was dressed very shabbily. I figure she probably couldn't afford medication. I thought, there for a week or two of medication, go I.

It depressed me a bit to think of how close I am to that situation, but it also made me appreciate GlaxoSmithKline and AstraZeneca.
