(Although the topic as given was "Something That You Miss," the "that" in that phrase was not really necessary. Do I miss a time when noticing things like that didn't matter? I don't think I ever have had a time where things like that didn't matter.)
What do I miss? I miss friends who live far away. I miss the free time I had a couple years ago (when I was working part time, and I eventually discovered that I also missed having money). I miss Boris and Natasha.
