I've always had difficulty with estimating time. I think, sometimes, it is related to my total inability to judge portion. But, it probably has to do with long term effects with lab-induced trauma.
When I was a young monkey, I could give you dates of significant events. But, if you asked me how much time elapsed between the dates, I couldn't tell 2 months from 6 months. Even if I'd just rattled off the dates to you.
This condition exists today. And, even though I know, intellectually, that I'm in error, I don't much care to fix it.
See, if you ask me about my recent bereavement . . . I will say "in the last year, I've lost two of the most significant relationships in my life." Only, the Old Woman died over a year ago. And, my dearest friend and buddy died in August. They died within the same year of each other . . . but I think for a while yet, it will be within the last year in my own mind.
As this family oriented holiday approaches . . . I spend more time wishing I believed in heaven . . . because then I could imagine the Old Woman and my buddy together. Then, I remember I don't believe in heaven. And it sucks.
