I (Cat) particularly miss our Outdoors club a lot. Where Tom and I met. Where lots of our friends are. A big part of my life which kept me healthy and sane. We haven't yet found anything like it here, even with all there is to do in California - Yosemite and such.
I also miss work. The work itself and my work friends. Job hunting here has been somewhat fruitless, or maybe I'm just being a bit picky. Maybe my expectations about the timeframe within which I would have started working or secured a job were unrealistic and I'm disappointed in myself.
Thank goodness for social media as we've been able to keep in touch with most people via this, but it's time to start getting into things here.
