Sorry to hear about your sister. I am sure it has not been easy, even the task of dispursing of her items she cherished.
I am not sure I am a loner, I spend a lot of time alone, but I prefer being in the company of others and thrive on it. I was in the work force until a month ago due to permanent layoff. Missed the conversation and people. But slowly I don't anymore and dont want to get out there and find another job. (Thank goodness I dont have to-we will never be very well off, but DH and I know being happy is more important than having things.) I have all of your posts to read and reply to. I feel like you are sitting across the table from me sipping on coffee in the morning, tea in the afternoon, and margaritas or a glass of wine at night. (Wish that were true.) Nope, I am not a loner.
