ANOTHER REASON WHY NORMAL PEOPLE DON'T EXIST, BUT RATIONAL PEOPLE DO.

Mary and Sally work in the same office, and at 5pm on Friday, the weekend begins. Both are single women.

Mary's weekend consists of Friday night drinks with friends, Saturday lunchtime coffee and lunch with a friend and a friends' afternoon at the movies followed by dinner out. On Sunday, Mary has lunch with friends and coffee with another friend, and goes home to prepare for the week.

Sally leaves the office at 5:30pm, once everything that's her responsibility is cleared up and goes home. She has a meal and sits in front of the television while sipping two glasses of wine. On Saturday, she does some housework and engages in some hobbies to recover from the week, needing solitude.

Mary is an extrovert; Sally is an introvert.

Who am I more like? Well, by nature I'm an introvert, but I reach out to marginalised people and if I'm with people who share my outlook on life, I can feel energised, but I need a lot of downtime afterwards.

My parents are happy to have my brother, sister-in-law and nephew over whenever, while I'm more, "Okay, you can come over for a bit of time on Wednesday and Sunday, but it has to be prearranged, it can't be spontaneous. So, if you ring me on Tuesday and ask if I want a visit in an hour, I'll have to say no." If my nephew was school age, I would say, "Okay, you can come and see your Aut-Uncle for a bit Wednesday afternoon, after school. But it has to be prearranged and if you can't one Wednesday afternoon, see if you can hold off to the next, please."

If "normal people" existed, people would be either extroverts or introverts and someone who wasn't whatever the norm was considered to be would be considered different.
