UPDATE: I suspect somebody just had a quiet shot at me about not being very self reflective. If that's the case, then I think they don't know me as well as they think they do.
The things suck the life out of me. It's just a fact. My major activity in a public get-together is to preserve my energy. Most people don't notice or care and that's a good thing. It's why I try to slide in quietly. Like when you slice a major gash in your arm - move slowly and don't allow that blood to spurt out of you. Interrupting my quiet entry is like exanguination. A true "Dexter" moment.
For sure there are great returns that come from socialising. I make most of my money by being a social animal and many of the people who would be friends cannot believe when I say this drains me.
And I thank God for the half a dozen or so people who care enough to understand this about me, and don't try to force me into their framework of friends and family. You know who you are.
To the rest - I probably like (or maybe even love) you. And one day we might even understand each other.
