enjoying the late afternoon or early evening...

Some good friend of mine (yes, you M.) told me once that being scientists we got right to behave little bit eccentric, but at the same time we got tendency to introversion, as we spend so much time by ourselves.
It is all true and I have to admit that I love quiet afternoons/evenings in almost empty building...

I have to be alone very often. I'd be quite happy if I spent from Saturday night until Monday morning alone in my apartment. That's how I refuel. - A. Hepburn
