I'm not so sure I would catorgorize this as being a "loner". I can only speak for myself, but if you are like me, you come home from work and all I want is some peace and quiet and to do something for "me"! Sometimes you just need solice in yourself. If that means being a loner, then so be it. I call it taking care of #1. My DH is great when it comes to my quilting. Sometimes he joins me and watches TV while I quilt, sometimes he goes to another room to read by himself. Does that make him a loner? We all need an escape and this is what makes all of us great! I'm sorry for your loss. Your sister was very lucky to have you in her life.
