I've not seen her since Friday night. This is only the second time she has not returned. The first time she did not show up for a day. Given that it's been three days I'm guessing she has flown away or gotten hurt, hopefully the first. I don't know much about their habits other than what I've seen. The only thing that has changed is that the lake was frozen for a couple days. Perhaps that would be enough for her to leave? I had not expected that though.
I'm really bummed about it. I suppose I knew this day would come sooner or later but that doesn't really make it any easier. I find myself looking down at the lake constantly hoping I'll see her. Ugh.
