I'm in this catagory too. I do chat on the phone with my aunt a few times a month for a few hours at a time, with a friend in Montana about once a month for a short time. Other than that I really don't talk with people much. I do shop on occasion by myself or with DH.
Talk with my Gracie ( my dog ) when I feel I need an outlet, she is a very good listener & never has anything bad to say, just lots of kisses! :-)
