I really hate talking on the phone... Always have really, but more and more so as I get older.
I have to talk on the phone for hours and hours as part of my job; it's the absolute last thing I want to do when I'm not working
Even if I love you and you're a great friend and we haven't talked in a while... I still hate talking on the phone, and unless there's something specific to talk about, if you call me, I'm likely to say ten words (four of which are likely to be SSDD) and then beg off.
I make an exception for my less technical relatives, with whom I generally can't communicate via email, IM, or Facebook; and with whom I will have long phone conversations a few times a year... But that's pretty much it.
There are times when I simply cannot stand to talk with ANYONE on the phone, or even via instant message... sometimes for a few days at a time. My head just feels like exploding even thinking about picking up the phone.
When I am feeling like that, I will simply not answer the phone or IM for anything other than emergencies or critical work calls. I cancel my con calls, I don't even listen to voicemail never mind respond (oh and DON'T leave me voicemail unless its an emergency and its the only way you know how to contact me. IM, email, or TXT me... I LOATHE voicemail no matter what mood I'm in).
If I am in one of those moods... I am not avoiding you, I just REALLY DO NOT WANT TO TALK ON THE PHONE... Just EMAIL me. I can respond to you properly when I have time and when my head feels better.
Believe me... Its not you I hate.... Its the gods be damned telephone.
