hibernation instinct? not exactly

[fflo]

For several days now I've been feeling, off and on, some kind of home-hangin' desire. Don't know what it's about, but I don't think it's the weather. There seems to be an aspect of withdrawal from social activity, though not entirely (thank goodness); I actually find myself sometimes preferring my own company to the idea of that of anyone else. I am not used to this feeling! What is it about?

I laugh at myself, with the big question mark over my head & a goofy, furrowed-brow expression.
