How much of my day did I spend completely alone?

2012:
I spend most of my days completely alone. At work, it's just me. Janis is usually on phone most of the day, so I hardly see her unless I really need to talk to her about something. When I get home, kids are in their own rooms, doing their homework. JK is working late tonight, so, it's just me in my room. Yes, me being people person, it does get lonely.

2013:
Today, I hardly had much time to myself. Woke up at 4:30 and went for workout. Then, to work (which was a bit lonely). After work, went to Christmas party back at workout place. There was tons of people at the party. I didn't get home till almost 11:30!

2018:
About half a day. Went to work out at 7 and then, straight from there, I went to Homegoods for shopping and visiting friends. After that, stopped by at Nordstrum Rack. By the time I got home, it was noon. In half an hour, I fell asleep and by the time I woke up, JK had left. So, I was pretty much on my own rest of the evening.
