You see now, just like the more 'open' folk don't get locking front doors, I don't get NOT locking the door.
And yes, I do like to be sounded out before being visited, and I loathe the assumption that because I'm a mother and one stop away from full on agoraphobia I'm open all hours to random visitors. I'm not. I'm receptive only when it is mutually convenient, and sometimes I just don't want to see anyone at all.
Not because I don't like you. But because I live with depression, anxiety, and I am what I am and I have to have the right 'frame', otherwise I'll just sit there mumbling and jiggling until you go away. Plus to me 'just dropping by' is 'just fecking rude' (probably another one of my 'things'...)
I'm sure all of these can be traced back to childhood events as well as more recent ones and my ishoos, but if I'm not prepared and in the frame, I find being around people quite painful and yes, sometimes irritating. Some might say I'm phobic.
This is also part of the reason I don't like leaflet drops, junkmail, chuggers, spam and coldcalling. I have my castle, and I simply don't want it invaded.
You can tell me that I'll be a lonely old lady, but I hopefully won't be. My family and friends know what I'm like and accept it. Those that matter don't mind, and those that mind don't matter (they also get to go on the shitlist). My doctor would probably like to plaster some label or syndrome on me but hey, whatevs. :o
