I'm a loner as well. Very quiet, on the out skirts, observer. Slow to warm, as in probably not until years of knowing someone will I let my guard down. But when I do I hold fast and get hurt deep when something happens to add distance. I just found out tonight that my sister will be moving far away. She knows and understands me and I trust her with everything. She is my closest friend. Perhaps it keeps me from feeling like I need to know others. I'm just really sad she is leaving. And sadness always feels like an insatiable cavern to me.
