The no-update update

No news on the adoption; the birth mom's due date is Wednesday.

Work is good. Very busy learning new role, but it's do-able.

And a whole lot of nothing else is going on.

Public transportation - etiquette question

So, let's say you get on a crowded train or bus, and you take a seat next to someone. As the train continues its journey, it gets un-crowded and empty seats become available; you could get up and move to one where you won't be sitting next to someone.

Is it okay to do that? I tend to stay where I am based on some strange belief that the person I'm sitting next to will be offended.
