I too am primarily an introvert in overall nature but I do get into extroverted phases especially during maniac states. In the past I have found myself in jobs requiring me to be 100% extroverted all of he time and it is tiring. It is also the reason I had to reevaluate my career, taking this into account, for a better fit.

I had to laugh though about the couples who argue over the phone, one likes to answer all the time and one says to let it go. I am always that "let it go" person in the relationship and have usually dated people who must answer it; many discussions over this. It was a good chuckle. Thanks!
