What I miss isn't a person. It isn't a place and it isn't a time. What I miss isn't really a feeling or an emotion... what I miss, and only realized I missed once I had a brief shot at reclaiming it, is a state of being.
I miss shopping for sheets and for kitchen items. I miss making comments about terrible movies, fashion trends and politics. I miss knowing that if I don't show up for something someone will care enough to try to find me. I miss speculation about a future, off-handed...
