I have several acquaintances that are ultra-Sanguine. This is that temperament that has never met a stranger and you are the most important person to them...until someone else comes along. They are comfortable with everyone and always seem so at ease and 'engaged' in conversation.
I also had what I would consider a 'best friend' that is a Sanguine primarily. We had been friends for 27 years and then suddenly she stopped speaking to me. I'm still not exactly sure why, though I'm pretty sure it had to do with our temperament differences. I am much more aggressive and a tad (LOL) moody. She goes with the flow.
In any event, it broke my heart that she won't speak to me.
The thing with Sanguines is they are typically the people you meet first because they are so outgoing! But soon you realize EVERYONE is their best friend and it's sad to be uncertain if they would even be available if you needed them. So in our new church I watch, (honestly) with some envy, the Sanguines and their friends and I wish I could be like them.
I realize in my heart God made us all different for a reason. You see, while Sanguines are awesome at being friendly and outgoing...they don't necessarily feel empathy as deeply as some of the other temperaments and as I mentioned they don't just have a few friends, EVERYONE is their friend (or wants to be).
I am trying to truly embrace who God created me to be and I know, beyond any shadow of doubt, that I am not a Sanguine, alas, and never will be.
