I find I can be quite dismissive, once in a blue moon I do go out and I can make myself socialize but I pay for it later with mental fatigue because it takes everything I have not to take my focus inward, stare blindly and drown out the stimulus. Sometimes it creeps up on me and I do just that though, when I need to take a break and it's already been a big day or something.
But there are some people that I have in the past, quote: "Cut Down" as friends have told me, These people are usually guys making advances that I'm just not that into and after I've tried to be 'subtle' (*snort* like a brick) in my 'rejection'. Apparently I can be harsh...LOL
Meh:shrug:
When people (New acquaintances) want to stay in touch, I don't mind at all, there are a lot of nice people out there... but it will never be me that will make the effort, not because I don't like the person or anything but it just the thought never crosses my mind down the track, I rarely think about people who have only graced my life momentarily. I guess I'm an out of sight out of mind kinda girl.
I have to make a conscious effort to occasional drop a line to friends I've had for years because it's the right thing to do not because I feel a hankering to keep in touch. Luckily I have true friends that actually like me worts and all and accepted me long before my weirdness had a name.
